成层Gibson地基中单桩沉降的非线性分析
Nonlinear analysis of settlement of axially loaded single pile in Gibson soil
摘要
Abstract
Based on principle of minimum potential energy, the government equations of single pile's load-settlement response are established. The solution of the pile-soil system obtained by using analytical form for soils displacement and difference scheme for pile. The effect of soil's nonlinearity on settlement response is considered by assuming that soil is linearly elastic-perfectly plastic. And the corresponding computer method is proposed. Then a program is developed based on Maple software. According to the numerical examples, the influences of soil parameters and slenderness ratio of pile on the settlement response are studied. The proposed method is used to analyze a full-scale static loading test pile; and the predictions are in reasonable agreement with the measurements.关键词
