Soil Mechanics for Unsaturated Soils


Book Description

The principles and concepts for unsaturated soils are developed as extensions of saturated soils. Addresses problems where soils have a matric suction or where pore-water pressure is negative. Covers theory, measurement and use of the fundamental properties of unsaturated soils--permeability, shear strength and volume change. Includes a significant amount of case studies.







Laboratory Soils Testing


Book Description

This manual presents recommended testing procedures for making determinations of the soil properties to be used in the design of civil works projects. It is not intended to be a text book on soils testing or to supplant the judgment of design engineers in specifying procedures to satisfy the requirements of a particular project, although it has been used in basic soil mechanics courses. Test procedures included are Water Content, Unit Weights, Void Ratio, Porosity and Degree Of Saturation, Liquid and Plastic Limits, Shrinkage Limit Test, Grain-size Analysis, Compaction Tests, Permeability Tests, Consolidation Test, Swell and Swell Pressure Tests. Drained Direct Shear Test, Triaxial Compression Tests, Determination of Critical Void Ratio, Unconfined Compression Test, Modified Providence Vibrated Density Test, and Pinhole Erosion Test for Identification of Dispersive Clays.

Geotechnical Instrumentation for Monitoring Field Performance


Book Description

The first book on the subject written by a practitioner forpractitioners. Geotechnical Instrumentation for Monitoring FieldPerformance Geotechnical Instrumentation for Monitoring FieldPerformance goes far beyond a mere summary of the technicalliterature and manufacturers’ brochures: it guides readersthrough the entire geotechnical instrumentation process, showingthem when to monitor safety and performance, and how to do it well.This comprehensive guide: * Describes the critical steps of planning monitoring programsusing geotechnical instrumentation, including what benefits can beachieved and how construction specifications should bewritten * Describes and evaluates monitoring methods and recommendsinstruments for monitoring groundwater pressure, deformations,total stress in soil, stress change in rock, temperature, and loadand strain in structural members * Offers detailed practical guidelines on instrument calibrations,installation and maintenance, and on the collection, processing,and interpretation of instrumentation data * Describes the role of geotechnical instrumentation during theconstruction and operation phases of civil engineering projects,including braced excavations, embankments on soft ground,embankment dams, excavated and natural slopes, undergroundexcavations, driving piles, and drilled shafts * Provides guidelines throughout the book on the best practices
