Abstract:

It puzzles us how to introduce the soil among piles in foundation design for high-rise building. Based on the in-situ measurement on MBA High-Rise Building of Nanjing University, we know some distribution rules of settlement, earth pressure among piles, pressure at pile-top, steel bar’s inner force and the ratio of load bearing by piles and soil among piles; and it is shown that the high-rise building can adopt the sparse pile foundation. These results can be used in foundation design and theoretical research of high-rise building.

Key words: high-rise building, sparse pile foundation, pile-raft foundation, in-situ measurement
