In this book, the authors present a review of the methods used for the solution of problems of stability and support of mine workings, based on the study and analysis of the validity conditions of individual theoretical computing procedures. The classification of these methods, based on the analysis of factors determining the behaviour of a system of mine openings, should contribute to the greater objectivity of decisions connected with the management and control of mining operations and, from the educational point of view, enable the intricate problems of stability to be better understood. Chapters dealing with support structures and technologies of support review the present state of the art with special reference to problems prevailing in Europe where mining is carried out under continuously deteriorating and less favourable natural conditions. The authors have assembled the theoretical and practical knowledge necessary for those to whom the book is addressed, namely, practising mining engineers and project managers, and students and graduates in mining colleges and schools.

Methods of Foundation Engineering covers the theory, analysis, and practice of foundation engineering, as well as its soil mechanics and structural design aspects and principles. The book is divided into five parts encompassing 21 chapters. Part A is of an introductory character and presents a brief review of the various types of foundation structures used in civil engineering and their historical development. Part B provides the theoretical fundamentals of soil and rock mechanics, which are of importance for foundation design. Part C deals with the design of the footing area of spread footings and discusses the shallow foundation methods. Part D describes the methods of deep foundations, while Part E is devoted to special foundation methods. Each chapter in Parts C to E starts with an introduction containing a synopsis of the matter being discussed and giving suggestions as to the choice of a suitable method of foundation. This is followed by a description of the methods generally used in practice. Simple analyses of structures, presented at the conclusion of each chapter, can be carried out by a pocket calculator. This book will prove useful to practicing civil and design engineers.

Abstract: Grouting is a construction process by means of which the highly erratic permeability and deformability of foundation rock and soil are homogenized. The main parameter governing the design and construction of grouting works is the permeability of the rock or soil, which is established by means of field permeability tests. This book assembles information on rock and soil grouting from various sources, together with the author's personal experience on several grouting projects. Some aspects of permeability testing of rock and soils are elaborated, and the use of theoretical ground water percolation studies for clarification of design options for grout curtains are presented. The results achieved by grouting are presented and analysed on examples of constructed grouting works (curtains, tunnels, foundations, lifting of structures). Particulars of the performance of the permeability tests and their evaluation are studied in some detail, since they can very much distort the results obtained, and thus lead to erroneous design assumptions. Systematic grouting and adjustment of the injection process to the development of grout consumption and pressure during injection is discussed in connection with the achievement of the required permeability standard. The application of grouting to reduce the permeability and the deformability of the foundation of dams and hydrotechnical structures is presented, together with a number of illustrative examples. Characteristics of contact and consolidation grouting of dam foundations and tunnel linings are described. The possibilities and examples of rock prestressing by means of grouting are reported, and the results from several applications are discussed. Examples of lifting and levelling leaning structures by means of grouting are also reviewed. The book is illustrated by 180 drawings and 20 photographs, and a list of symbols used in the formulae, plus a glossary of specific terms use

The object of this book is to shed light on the most important design aspects encountered in foundation engineering and to present basic design principles representative of the developed part of the world. Modern geotechnical investigation methods and their interpretation are exemplified. The philosophy of the new European code for geotechnical design is presented. The most important and practical aspects of ground modification techniques are included. This book can be used as a textbook for senior undergraduate and graduate students. It can also serve as a combined text- and handbook for professional engineers working in the field of geotechnical engineering. Line drawings and photographs accompany the text.

In this volume, soil creep is analysed within the framework of other soil-rheological phenomena, such as stress relaxation and long-term resistance, to present an in-depth discussion of the effect of time on soil behaviour. As time is the only state parameter which cannot be entirely modelled in the laboratory, the presented extrapolation is based upon a combination of appropriate theoretical analysis, and the principles of the physical behaviour of soils affected by state parameters such as porosity, water content, stress, strain, time and temperature. Principal macro- and microrheological theories are analysed, and a comprehensive picture of the soil structure and of the effect of state parameters is presented, documented by the author's experiments and illustrated by many examples. The theory of hereditary creep was selected as the best theory serving the author's purpose to propose simple constitutive relations governing creep of soils. The proposed constitutive relations have been implemented into FEM programs and the effect of the time factor has been demonstrated by the solution of such boundary value problems as a dams and underground tunnels. This volume should be of interest to civil engineers, scientists, research and postgraduate students, and advanced undergraduates.

Dams and Earthquakes deals with the association of earthquakes and large artificial lakes, particularly on the part that pore pressure plays in inducing earthquakes. The book also contains methods for recording seismic activity, before, during, and after the filling of reservoir dams through the installation of a network of portable seismographs. The text assesses the parameters and macroseismic effects of the Koyna earthquake in India in December 1967, as well as the instrumental and macroseismic data showing that the Koyna earthquake is a multiple seismic event. The book investigates the geology, hydrology, and seismicity of seismic reservoir sites, including three cases of induced seismicity after fluid injections in deep wells. A possible correlation between the reservoir level or volume of the injected fluid and the tremor frequency exists. The characteristic seismic features of reservoir associated earthquakes can reflect changes in the mechanical properties of rock masses near the reservoirs. The book also investigates the part played by increased pore-fluid pressures in triggering the earthquakes at Denver, Rangely, Kariba, Kremasta and Koyna. The UNESCO Working Group on "Seismic Phenomena Associated with Large Reservoirs" recommends the adoption of a two-phase planning in instrumental studies and surveys at sites to be used for large reservoirs. The book can be beneficial for meteorologists, environmentalists, geologists, civil engineers, structural engineers, or for officers of river and lake authorities.

Full title: CRC Pavement Design Manual.
Author: McCullough, B. F., and G. E. Elkins.
Publisher: Austin Research Engineers, Austin, Texas (1979).
Language: English
I'm writing this post because I'm currently facing a problem with choosing a new Laptop/Mobile Workstation. I've been using my current laptop since 2011, which is a Dell Inspiron N5110 (CPU Intel Core i7-2670QM, 8GB RAM, 256gb SSD and GPU Nvidia Geforce GT525m). I use it for running ETABS v15, SAFE, SAP2000, AutoCAD 2D, TEKLA Structures (currently learning) and sometimes to open and check REVIT Models.
The point is that I don't really know whether choose a gaming laptop with a Nvidia Geforce GTX 960/970 M or a Mobile Workstation with a Nvidia Quadro M1000M Β (maybe an ATI FirePro w5170), since there's not much information about the performance of previously mentioned workstation GPU. To make things worse, I'm not able to spend more than 900-1100 dollars right now.
The question is, which one of these GPU-CPU combinations would you recommend me for my next laptop upgrade?
