supporting, capacity, earth
The supporting capacity of different earth formations varies from several tons per square foot solid rock to nothing (in fact for saturated silt. The purposes of investigating a foundation site are:.1) to discover a stratum on which the foundation may be placed most economically.
2) to determine the properties of that stratum.
3) to determine the level of the ground water; 4) to determine the possibility of the support to the bedding stratum within the range of the stress distribution. The laboratory analyses of soils are absolutely necessary, their chief purpose is to examine the probable behaviour of the soils under changing conditions of moisture.
