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.

Advanced Dam Engineering for Design, Construction, and Rehabilitation


Book Description

The present state of the art of dam engineering has been ronmental, and political factors, which, though important, attained by a continuous search for new ideas and methods are covered in other publications. while incorporating the lessons of the past. In the last 20 The rapid progress in recent times has resulted from the years particularly there have been major innovations, due combined efforts of engineers and associated scientists, as largely to a concerted effort to blend the best of theory and exemplified by the authorities who have contributed to this practice.
