切线模量法在单桩非线性沉降计算中的应用
Application of the Tangent Modulus Method to Nonlinear Settlement Calculation of Single Pile
摘要
Abstract
In order to better calculate the nonlinear settlement of single pile , a method is presented in this paper , in which the settlement of single pile is divided into the compression of pile and the settlement of pile end soil according to the standard method , and the settlement of pile end soil is calculated by tangent modulus method .The tangent modulus is obtained by in -situ test, so the characteristic of the undisturbed pile end soil can be reflected .What is more , the effects of different stress level is considered by the tangent modulus , so the nonlinearity of settlement of pile end soil can be also reflected .Through the engineering example , it is indicated that using the tangent modulus method to calculate the nonlinear settlement of single pile is feasible .关键词
