湿陷性黄土地区单桩沉降数值模拟研究
Numerical Simulation Study on Settlement of a Single Pile in the Collapsible Loess Ground
黄土湿陷性会导致风电桩基础的变形失稳。而本文依托于工程实例，通过单桩静载试验，探究了单桩承沉降和轴力的变化规律。并以静载试验为基础，利用ABAQUS有限元软件对湿陷性黄土地区单桩进行数值模拟，并结合单桩静载试验数据进行对比分析，结果表明数值模拟与试验结果较符合。
ollapsible loess can lead to the deformation of the pile foundation of the wind turbine. Based on the single pile static loading test in the project, the changing rule of settlement and the axial force on the single pile was studied. And using the ABAQUS finite element software for numerical simulation of single pile in collapsible loess region, which was on the basis of static load test, and comparing with the single pile static load test data and analyzing the data, results show that the numerical simulation data agree well with experimental results.
