利用通用有限元计算软件ANSYS进行分析,采用固定支座模型,人为地给柱脚支座以支座沉陷,以此模拟不均匀沉降.对框剪结构在采动引起的3种不同地表变形作用下进行了计算,得出了结构在不同地表变形作用下,上部结构内力的变化及分布规律.为研究采动影响下地表变形对建筑物的影响提供参考.
In this paper,an artificial support subsidence is provided to the column base by means of the fixed support model and the ANSYS software so as to simulate the uneven settlement.Through calculating the frame-shear wall structure under the action of the three different surface deformations induced by mining,this paper points out the change and distribution rule of internal force in the superstructure,which serves as a reference for the study of the impact of surface deformation caused by mining on the buildings.
