摘　　要：岩溶山区风机基础工程的建设面临着土岩组合不均匀地基的问题,而且作用在风机上的风荷载随机性较大,风机地基基础设计难度较大,文中采用ABAQUS有限元软件对土岩组合地基上风机圆形扩展基础沉降规律进行了数值模拟,得到了土岩组合地基上风机基础在不同荷载作用方向下的沉降规律,模拟结果可以为风机基础土岩组合地基设计计算提供一定参考。The construction of wind turbine foundation engineering in mountainous areas faces the problem of uneven soil-rock composite ground,in addition,the wind load acting on the wind turbine is very random,so designing for the wind turbine foundation becomes very difficult. This paper applied the ABAQUS finite element software to simulate the settlement law of the circular spread foundation of the wind turbine on the soil-rock composite ground, and the settlement law of the wind turbine foundation on the soil-rock composite foundation was obtained under different load directions, which provides a certain reference for the design and calculation of the soil-rock composite ground under the foundation.
