西安地区单桩桩土相互作用数值模拟分析

THE NUMERICAL SIMULATION ANALYSIS OF PILE-SOIL INTERACTION OF SINGLE PILE IN Xl'AN AREA

随着计算机技术和数值方法的不断发展和完善,使有限元法得到越来越多的应用。根据西安地区原型摩擦桩的地层特点和土性条件,运用有限元基础理论,利用相应的边界条件与假设条件,建立单桩数学模型。通过模型研究了单桩的沉降特性与土共同作用的影响因素,对西安地区单桩桩土相互作用机理进行了探讨。

According to the soillayer characteristics used for friction piles in Xi an area, the single pile model was built using FEM method corresponding to boundary conditions and assumptions. The factors affecting the interaction of single pile settlement characteristics with the soil are analyzed, and the mechanism of pilesoil interaction and the pile settlement were studied through this model.
