摘要
Abstract
Argillaceous siltstone and mudstone soft rocks are widely distributed in Changsha area,which have the characteristics of"neither soil nor rock".For the selection of pile foundation in soft rock area,rock-socketed pile and friction pile are often discussed.In this paper,rock-socketed pile and friction pile are used respectively to calculate the pile length,and it is more reasonable to use rock-socketed pile for large-diameter soft rock cast-in-place pile.The influences of rock strength,soil friction resistance and rock integrity on pile length and bearing capacity of single pile are analyzed to provide suggestions for the design of pile foundation.关键词
