摘要: 在地震作用下,地下结构的地震响应影响因素复杂多变,地下结构的埋深就是其中之一。针对地下结构埋深对地下结构的地震动响应的影响,通过建立处于不同埋置深度的2种结构模型,运用FLAC软件进行数值模拟研究。研究表明,在地震作用下,同一位置的地震波,在保持入射波不变的情况下,当地下结构位于不同的埋置深度时,结构上相同位置的地震响应差别不明显。

Abstract: Under the seismic action, factors affecting the seismic response of underground structure are complicated, among which the embedded depth of underground structures is taken into consideration. In order to know effects of embedded depth on seismic response of structures, we established two models with different depths, using the FLAC software for numerical simulation. The research result shows that, for given position of seismic wave, responses for underground structures at different embedded depths tend to be not obviously different under the conditions of unchanged incident wave.

Key words: embedded depth, underground structure, seismic response, difference and similarity, FLAC software
