[资源] Advanced Unsaturated Soil Mechanics and Engineering

Book overview
Civil engineers build on or in the earth’s surface. Most of the earth’s land
surface comprises notoriously hazardous geomaterials called ‘unsaturated
soils’. These soils are a hazard to earth structures and earth-supported
structures because on wetting, by rain or other means, they can expand or
collapse with serious consequences for cost and safety. This book puts the
mechanics and engineering of unsaturated soils into a logical framework
for civil engineering analysis and design. It also explains the laboratory and
field testing and research that are the logical basis of this modern approach
to safe construction in these hazardous geomaterials.
This state-of-the-art book is written in four parts as follows:

1. Physical and flow characteristics of unsaturated soils;
2. Collapse, swelling, shear strength and stiffness of unsaturated soils;
3. State-dependent elasto-plastic modelling of unsaturated soils;
4. Field trials and numerical studies in slope engineering of unsaturated soils.

This book is unique because:

• it illustrates the importance of state-dependent soil–water characteristic
curves;
• highlights modern soil testing of unsaturated soil behaviour, including
accurate measurement of total volume changes and the measurement of
anisotropic soil stiffness at very small strains;
• introduces an advanced state-dependent elasto-plastic constitutive
model for both saturated and unsaturated soil;
• demonstrates the power of numerical analysis which is at the heart of
modern soil mechanics;
• studies and simulates the behaviour of loose fills from unsaturated to
saturated states, explains the difference between strain-softening and
static liquefaction, and describes real applications in unsaturated soil
slope engineering;
• includes purpose-designed field trials to capture the effects of two independent stress variables, and reports comprehensive measurements of
soil suction, water contents, stress changes and ground deformations in
bare slopes;
• introduces a new conjunctive surface and subsurface transient flow
model for realistically analysing rainfall infiltration in unsaturated soil
slopes, and illustrates the importance of the flow model in slope engineering.
