摘要

目前为止还没有成熟的地下结构抗震性能评价方法。本文结合地下结构地震响应的特点及已有相关规范,初步建立了地下结构抗震性能评价方法。并以某人防工程为例,建立三维分析模型,计算其在两种不同幅值的人工合成波作用下的三维地震响应,计算了结构的水平横向相对位移,评价了该人防工程的抗震性能。评价结果表明此人防工程具有良好的抗震性能。本方法可供其它相关地下工程参考应用。
Up to now there is no standard evaluation method for evaluating seismic behavior of underground structure.In this paper an evaluation method for seismic behavior of underground structure is built based on the characters of seismic response of underground structure and some relative national standards.Taking a civil air defense engineering as example,a three-dimensional analytical model is built,and the three-dimensional seismic responses under two different artificial waves are calculated.The result gives the relative horizontal displacements of the beams,evaluates the earthquake resistant capability of the engineering.The result shows that the civil air defense engineering has a good seismic behavior.The method may provide reference to other relevant underground engineering.
