[Image: info.png]
Linear Algebra, Geodesy, and Gps
Wellesley College (October 1, 1997) | ISBN: 0961408863 | 624 pages | PDF | 6 MB

Linear Algebra, Geodesy and GPS discusses algorithms, generally expressed in MATLAB, for geodesy and global positioning. Three parts cover basic linear algebra, the application to the (linear and also nonlinear) science of measurement, and the GPS system and its applications. This book has many strengths. It offers a variety of points of view. It is complete, helpful, and you may find an explanation that appeals to you. .A popular article from (June 1997) "The Mathematics of GPS" is included as an introduction. Annotation c. by Book News, Inc., Portland, Or.

Part I: Linear Algebra. Chapter 1: Vectors and Matrices; Chapter 2: Solving Linear Equations; Chapter 3: Vector Spaces and Subspaces; Chapter 4: Orthogonality; Chapter 5: Determinants; Chapter 6: Eigenvalues and Eigenvectors; Chapter 7: Linear Transformations. Part II: Geodesy. Chapter 8: Leveling Networks; Chapter 9: Random Variables and Covariance Matrices; Chapter 10: Nonlinear Problems; Chapter 11: Linear Algebra for Weighted Least Squares; Chapter 12: Constraints for Singular Normal Equations; Chapter 13: Problems with Explicit Solutions. Part III: Global Positioning System (GPS). Chapter 14: Global Positioning System; Chapter 15: Processing of GPS Data; Chapter 16: Random Processes; Chapter 17: Kalman Filters.

Posted by: stigtg - 07-07-2010, 12:11 PM - Forum: Archive Problem - Replies (3)

Does anyone know how to render rebar in Revit Structure 2010.I tried everything(well nearly everything) but still can't get no results.Rebars are created with Revit extension,option "Automatic Reinforcement Generation".
I can see rebar in 3D view(view unobscured box checked).I you have any suggestion,please share.

Posted by: pant23 - 07-07-2010, 09:43 AM - Forum: Archive Problem - No Replies

Hi to all. I want to ask a question about this program. I have a tunnel (TBM) and i want to find the axial stiffness (EA) and the flexular rigidity (EI) of the segmented lining (rings). The young modulus is known (35 GPa) and i want yr opinion about this.
Thank u

  An Approach to 1g Modelling in Geotechnical Engineering with Soiltron
Posted by: georoyo - 07-07-2010, 05:57 AM - Forum: Archive - No Replies

Can any one get it the following book, its very needful.

An Approach to 1g Modelling in Geotechnical Engineering with Soiltron
by Andreas Laudahn.

# Publisher: Logos (December 15, 2005)
# ISBN-10: 3832510729
# ISBN-13: 978-3832510725
# ASIN: B001T45BQO

Description:
Complex problems in geotechnical engineering and soil mechanics can be investigated with physical modelling, where the structures in a geometrically n-times smaller scale are reproduced and the occuring forces and deformations are measured. Problematic is the reduction of pressures and the subsequent change of the mechanical behaviour of the model soil. The versatility of field and model test is shown by examples from the literature. In this thesis the similarity between barotropy and pyknotropy was used to model prototype soil behaviour. Soiltron is a prototype soil, which is treated with light and soft additives to achieve the same relative density in the model at an n-times smaller pressure as in the prototype. The stiffness and strength of the new material can be influenced to simulate prototype material behaviour by the control of the soil density. Thus, the use of that soil as material in small scale models is possible. At the Institute of Geotechnical and Tunnel Engineering of the University of Innsbruck a model soil material was not available in sufficient quantity. Therefore, a large quantity of quartz sand was purchased and its mechanical behaviour was investigated in detail with triaxial test devices using local strain gauges. The specimen deformations were inspected with evaluation of remote measurements using PIV. Systematic and random test errors have been avoided or have been taken into account. Appropriate regressions have been found to relate pressure and density to the properties of the soil and to calculate the required density of Soiltron. The appropriateness of Soiltron is verified in two demonstration model tests. This work can be seen as foot step to strike a new path in physical modelling.

GUIDELINES FOR GEOTECHNICAL INVESTIGATION
UAE - ABU DHABI MUNICIPALITY ROAD DEPARTMENT

[Image: 07094452464897559985.jpg]

[Image: info.png]

This document is a compilation of recommended good practices for geotechnical investigation.
The document delineates the sequential stages that a normal geotechnical investigation program requires and describes the purpose and scope of work for each of those steps. Descriptions of technical requirements for site works, laboratory works, and reporting are covered in general.
Indexes of specific, internationally accepted standards1 pertinent to subsurface investigation are included in the appendices. This document is intended as a reference tool. The requirements and practices described are
general guidelines and are to be viewed as such. The document is not intended to be definitive in its scope or to provide detailed guidance on every type of subsurface investigation in every type of condition. Prevailing ground conditions and details of a project at hand will finally dictate actual requirements (see Section 3.3.2.6).
The contents of this document are based on good engineering practice and internationally accepted standards, and the Abu Dhabi Municipality Road Department (herein referred to as the Department) expects these practices and
standards, as applicable, to be followed as a matter of course in geotechnical investigations.
These should be considered minimum standards.
Specifications that are more detailed or standards that are more appropriate may be required, depending on a specific project’s needs.

Comprehensive Rock Engineering
Volume 1:Fundamentals

[Image: 13836949899184015238.jpg]

[Image: info.png]
December 1993 These volumes constitute an up-to-date and comprehensive work of reference concerning the relatively new field of rock mechanics. It brings together a body of knowledge not available anywhere else in one coherent publication. The five volumes consist of state-of-the-art articles written by the founding experts in rock mechanics and rock engineering, together with contributions from those members of the community currently exploring the latest theoretical and practical engineering design and construction methods. The five volumes each have a theme: Fundamentals; Analysis and design, Rock testing and site characterisation; Excavation, support and monitoring; and Surface and underground project case histories. There is a cumulative subject index. -- Tunnels & Tunnelling

December 1993 This work brings together knowledge from all areas of rock engineering to form a body of information not previously available in one source. It features more than 200 authors from 25 countries and covers both the scientific basic of rock engineering and rock mechanics and the application of this knowledge in the field. -- E and MI
Product Description
Engineers wishing to build structures on, or in, rock use the relatively new discipline known as rock mechanics. Comprehensive Rock Engineering is an authoritative and comprehensive work of reference containing a compilation of knowledge not available from any other source in one coherent publication. Clearly illustrated throughout, this multi-volume publication consists of state-of-the-art articles written by over 200 internationally recognized authorities and covers every aspect of rock mechanics and rock engineering. Comprehensive Rock Engineering is arranged in five volumes under the themes: Fundamentals; Analysis and Design; Rock Testing and Site Characterization; Excavation, Support and Monitoring; and Project Case Histories, providing the key information that is required for any rock engineering application. Case histories and principles relating to specific countries are also included.
