“Design & Testing of Rock socketed Piles: A Case Study from Mumbai”


Large diameter bored piles are frequently being used to support heavy and settlement sensitive structures. To achieve higher load carrying capacities, these piles are socketed into the competent rock strata. In the case of rock socketed piles, major share of the pile capacity is obtained from the shaft esistance and base resistance of the pile from socketed zone. In view of close proximity to the shoreline and poor and extremely variable geology of Mumbai city, rock socketed piles are being increasingly used to support many medium to high-rise structures. The depth of the rocksocketing mainly depends on the design load on the pile, depth of bedrock and quality of rock mass encountered in the socketed area. Rock socketed piles pose several challenges to geotechnical engineers in terms of identifying the bedrock level, as it is often related to the resistance of the rock mass to the chiseling or drilling tool. Deriving the design parameters of rock mass for use in pile capacity calculations, estimating the safe load carrying capacity of piles from pile load tests, and construction difficulties are other issues which need to be given due consideration forsafe design of rock socketed piles. Some of the recent experiences from Mumbai city will be discussed in this lecture with reference to an on-going foundation construction of a high-rise structure.
