Question
3. A soil layer consists of 4 meters of sand underlying 5 meters of clay. The water table is naturally located at the rock bed under the soil strata but rose by 6 meters due to a recent storm. Further, capillary action is expected to de- velop due to the nature of the soil in question. Compute the effective stresses at the end of expected capillary ac- tion, at the end of the water table, at the interface of the clay and sand and finally at the bottom of the soil strata. Pertinent soil properties are as follows:
SMART al al A 99 |4, 9:52 GLOBE 1. Consider Figure FTR 1 (Taken from Geotechnical Engineer- ing Design, Ming Xiao, strictly for educational purposes) shown. If the specific gravity of the soils are respectively from top to bottom 2.6, 2.7 and 2.73, estimate the effec- tive stresses at the mid thickness of each layer. 2. Still considering Figure FTR 1, estimate the additional stress- es induced by the footing on the mid thickness of each layer using both 2-1 approximation and graphical method as proposed by Boussinesq. 3. A soil layer consists of 4 meters of sand underlying 5 meters of clay. The water table is naturally located at the rock bed under the soil strata but rose by 6 meters due to a recent storm. Further, capillary action is expected to de- velop due to the nature of the soil in question.
