Soil Consolidation

CONSOLIDATION TEST OF SOIL

TO DETERMINE THE CONSOLIDATION CHARACTERISTICS OF A SOIL SAMPLE Theory: Consolidation of a saturated soil occurs due to expulsion of water under static, sustained load. The consolidation characteristics of soils are required to predict the magnitude and the rate of settlement. The following characteristics are obtained from the consolidation test. Coefficient of compressibility, Coefficient of […]

ELECTRO OSMOTIC CONSOLIDATION OF SOIL

Electro osmotic consolidation means the consolidation of soft clays by the application of electric current. It was studied and applied for the first time by Casagrande. It is inherent that fine grained clay particles with large interfacial surface will consolidate and generate significant settlement when loaded. The settlement creates problem in the foundation engineering. Electro […]

BACKFILLING, CONSOLIDATION & COMPACTION

Preparation The ground over which the filling has to be done should be cleaned off all grass, loose stones, rubbish of all kinds etc. If there is water in the area, it should be pumped or bailed out. If the plinth depth doesn’t exceed 45cm above ground level and if the exposed ground is B.C. […]

COMPRESSIBILITY AND CONSOLIDATION OF SOILS

When a soil mass is subjected to a compressive force, its volume decreases. The property of the soil due to which a decrease in volume occurs under compressive force is known as the compressibility of soil. The compression of soil can occur due to Compression of solid particles and water in the voids Compression and […]
