摘要

摘要: 采用大型通用有限元分析软件ABAQUS,对国电铁岭开发区风电场新建工程风机岩石锚杆基础进行有限元Pushover分析。探讨了其受力特性,与传统重力式基础的应力状态进行对比,同时与安装在其上的压电式结构健康监测系统的监测数据进行比对。结果表明：这种新型的基础与传统的基础相比较有很大的优势,完全可以替代传统的重力式基础；另外,结构健康监测系统运转正常,基础工作状态良好。

Abstract: The finite element pushover analysis on a rock anchor foundation of a wind turbo-generator located at Guo Dian Tie Ling development zone is numerically performed by using ABAQUS of a large general-purpose software. The mechanics characteristics of the rock anchor foundation are discussed and the stress states are compared with a traditional gravity foundation, meanwhile, the numerical results are compared with the received data from the PZT-based structural health monitoring system installed in the foundation. The results show that the new-type foundation has greater advantages than those of a traditional one and it may completely replace the traditional gravity foundation in the future. Furthermore, the structural health monitoring system is operating well and the foundation works in a good condition.
