Soil Mechanics: Basic Concepts and Engineering Applications is primarily designed as a main text for university students taking first degree courses in civil engineering as well as environmental and agricultural engineering. Emphasis is placed on presenting fundamental behaviour before more advanced topics are introduced. The special structure of the book, embodied in each chapter, makes it possible to be used in two, three and four year undergraduate courses in soil mechanics. However, as new and advanced topics that extend beyond standard undergraduate courses are included, the book will also be a valuable resource for the practicing professional engineer. A problem solving approach is adopted through all chapters and 152 worked examples demonstrate the engineering applications, simulate problem solving learning and facilitate self-teaching. There are 113 unsolved problems with answers set for solution by students.

This text is primarily meant to cater the need of undergraduate and postgraduate students of Agricultural Universities/Institutes in India and is expected to be of help to teachers and researchers as well. An endeavour has been made to provide sufficient theoretical background on the subject matter to ensure that the procedures are not followed merely to obtain a numerical answer.

Soils consist of solid particles, enclosing voids or pores. The voids may be filled with air or water or both. These three soil states (or phases) can be visualized by the enlargement of three small samples of soil.

In this chapter, the subject of ground improvement is introduced along with a discussion of the engineering parameters that can be addressed and a brief history of ancient practices. An overview of the objectives of designing a ground improvement plan is provided with a description of how ground improvement methodsmay be implemented into a project.The general categories and objectives of ground improvement techniques are also described. <...>

Soil mechanics is the science of equilibrium and motion of soil bodies. Here soil is understood to be the weathered material in the upper layers of the earth’s crust. The non-weathered material in this crust is denoted as rock, and its mechanics is the discipline of rock mechanics. In general the difference between soil and rock is roughly that in soils it is possible to dig a trench with simple tools such as a spade or even by hand.

Precise descriptions of the features seen in soils or regoliths as examined under the microscope require a specific set of concepts and terms because the microscope reveals features that simply cannot be seen with the naked eye. Microscopic features can of course be described using common words, but this would lead to very tedious and lengthy descriptive texts that are time consuming both to write and to read and not always unambiguous. Moreover, it would be difficult to translate such descriptions without losing information or committing errors. By using a comprehensive terminology, descriptions would be not only shorter, but also easier to compare and to store in databases <...>

В книге рассмотрены современные методы лабораторных, в том числе органолептических исследований основных свойств грунтов. Все представленные методы определения состава, состояния, структуры и свойств грунтов соответствуют ГОСТам, изложены в виде инструктивных, методических указаний и сопровождаются описанием приборов, аппаратуры и вспомогательного оборудования

В работе представлен анализ известных методов классификации грунтов с использованием параметров статического зондирования CРТ, CPTU: лобовое сопротивление, силы трения и поровое давление, измеряемое в основании конуса. Одним из наиболее распространенных, основанных на CPT, методов оценки типа грунта является диаграмма, предложенная в 1986 г. П.К. Робертсоном (P.K. Robertson) с коллегами, основанная на лобовом сопротивлении конусного зонда qс и коэффициенте трения Rf.

Методическое пособие к лабораторным работам предназначены для студентов направления подготовки 05.03.01 «Геология» специальности «Гидрогеология и инженерная геология». В работе приводятся описание порядка выполнения и обработки результатов лабораторных работ по курсу «Грунтоведение».
