Abstract
The stiffness-flexible pile composite foundation is not mature in theory, the current specification is the strength control design method, which calculation results have larger discrepancy from the actual, and the tangent modulus method is more practical on the basis of undisturbed soil. This article recommends the short pile cushion layer, which not only can meet the requirements of bearing capacity and set lement, but also can save cost.关键词
