矿震对建筑物影响三维有限元分析
|
摘要
通过数值模拟来研究矿震对建筑物作用的方法,根据抚顺老虎台矿区的矿震情况,选取抚顺市区一幢七层砖混结构住宅为研究对象,应用大型通用有限元分析软件ADINA建立了该结构的三维模型,并模拟了矿震对结构的影响,进行动力分析,求解得出各层层间位移,并将模拟值与现场获得的震害监测值进行了比较,两者吻合较好,验证了此种方法用来模拟矿震作用的可行性和准确性,对进一步研究矿震对建筑物的影响具有一定的参考价值。
To investigate the method of effect of mining-induced seismicity on the buildings using numerical simulation,according to the mining-induced seismicity which occurred in Fushun Laohutai Mine Area,a seven-story brick-concrete structure in Fushun city is selected for the study.3D model of the structure using finite element analysis software ADINA is established and the mining-induced seismicity effect on structure is simulated.Relative storm displacements of the structure are obtained through dynamic analysis and compared the simulated and monitored data aquired on site are compared and they agree with each other well.It proves that the simulating method for studying mining-induced seismicity is feasible and accurate.The method has some reference value for the further study on the impact of mining induced seismicity on buildings.
