地下结构抗震计算中拟静力法的地震荷载施加方法研究
|
摘要
分析了地下结构横截面抗震设计中常用的拟静力计算方法的误差来源。从地震时一维土层反应应力入手,对拟静力法中有限元反应加速度法的地震荷载加载方法进行改进,提出了有限元反应应力法。对某给定地质条件下的浅埋箱型地铁车站结构,用有限元反应应力法﹑反应位移法﹑有限元反应加速度法和有限元动力反应分析进行了对比计算。结果表明:有限元反应应力法最接近有限元动力分析结果,是一个精度较高的实用性很强的拟静力计算方法。
The pseudo-static approaches commonly used in the seismic design of underground structures were described and the sources of error in these approaches were analyzed respectively.Based on the response stress of one-dimensional soil layer,the finite element approach was improved and a response stress approach was put forward.To validate the finite element response stress approach,a comparison calculation was made for some shallowly embedded box-shaped structures of subway station under the given conditions by use of finite element response stress method,response displacement method,finite element response accelerated method and finite element dynamic analysis method.It was shown that the calculated result gained from the finite element response stress method was close to that from the finite element dynamic analysis method.Thus the finite element response stress approach was a practical pseudo-static one with high precision.
