This comprehensive text explores the technologies and developments in excavations for any type of surface or underground excavation. The first several chapters cover unit operations, including drilling, explosives and blasting, mucking, haulage, hoisting, and supports and reinforcement. The book then describes excavation techniques for various operations, such as tunneling, raising, sinking, drifting, stoping, quarrying and surface mining, underground mining, pillar blasting, and liquidation. It also examines the design, planning, and analysis of excavations as well as the construction of surface and subsurface excavations, such as caverns. Case studies focus on heavy underground blasting during pillar recoveries.

This design manual is one of a series developed from an evaluation of facilities in the shore establishment, from surveys of the availability of new materials and construction methods, and from selection of the best design practices of the Naval Facilities Engineering Command, other Government agencies, and the private sector. This manual uses, to the maximum extent feasible, national professional society, association, and institute standards in accordance with NAVFACENGCOM policy. Deviations from these criteria should not be made without prior approval of NAVFACENGCOM Headquarters (Code 04). Design cannot remain static any more than can the naval functions it serves or the technologies it uses. Accordingly, recommendations for improvement are encouraged from within the Navy and from the private sector and should be furnished to NAVFACENGCOM Headquarters (Code 04). As the design manuals are revised, they are being restructured. A chapter or a combination of chapters will be issued as a separate design manual for ready reference to specific criteria. This publication is certified as an official publication of the Naval Facilities Engineering Command and has been reviewed and approved in accordance with SECNAVINST 5600.16.

This book offers a thorough and systematic examination of theoretical and computational aspects of least-squares finite element methods. The range of topics spans from formal mathematical analysis and framework for least squares methods, application of this framework to concrete partial differential equations and discussion of the computational properties of the methods.
The abstract least-squares framework will help readers to first grasp least-squares methods, while the many numerical examples provide a valuable practical guide to these methods. Most of the necessary background material is contained in several appendices.

Abstract
A simplified method for the assessment of bending moment resistance for reinforced concrete (RC) members with circular cross-sections is presented. In the proposed method longitudinal rebars arrangement is replaced with a thin steel ring equivalent to the steel total area; moreover, according to modern codes, simplified stress–strain relationships for concrete and reinforcing steel are used.
The performed analyses demonstrate that the value of flexural capacity determined by the proposed approach, is very close to the results obtained by applying rigorous methods based on analytical and numerical algorithms.
The study also proves that in members subjected to bending moment without axial load, the flexural strength depends on the geometry of the section (i.e. radius and concrete cover) and on mechanical ratio of steel reinforcement by a very simple formula.
