Theoretical Simulation Approach for Load Settlement Characterstics of Piles in Shale Deposits
Subrata Ray, R.R. Maurya
A large number of power stations are being set up in Chandrapur area having coal deposits. Several industries are also coming up in this area. The subsurface is geologically formed under Gondwana system and consists of shale strata at depths ranging from 8 to 12 m. The stress deformation characteristics of shale exhibits wide variation because of its geological origin. In view of this, a study was conducted on bored cast in-situ piles installed for Switchyard project to evaluate load settlement characteristics of three test piles to understand the probable engineering behavior of the material at the tip and the sides. An approach is developed to simulate the load settlement behavior as observed in the field, theoretically. This is based on the concept of load transfer. The fit is obtained by varying the parameters, thus may be considered as iterative in nature. The theoretical curves closely matched the observed curves. The results of this study are presented in this paper.
