Abstract
Existing methods consider the intact rock properties for the analysis of rock-socketed piles. In the present analysis, a new method is proposed incorporating rock mechanics principles to study the load-settlement response of rock-socketed piles of Mumbai region using load transfer technique. As a rock-socketed pile is supported by the rock mass, it would be more realistic to consider rock mass properties in lieu of intact rock properties. The database of sixty cases depicting response of varying pile diameters is analysed and presented in this paper. Further, a full-scale pile load test case conducted in Mumbai region using O-Cell technology is analysed to study the performance of the proposed model. The method is capable of separating the contribution of skin friction from the weathered stratum and socket material and the point resistance.
