| 摘 要： | 以二维土质边坡模型为例,地震输入方式分别采取单点输入和多点输入,考虑其土层地震反应、主应力极值等特征,分析单点、多点输入的差异;在此基础之上,探讨单点输入与多点输入下坡高、坡角的变化对土质边坡模型安全系数的影响。结果显示,在地震工程抗震设计时采用多点输入比单点输入更加安全、更符合实际情况。

| Abstract: | In this paper,we take the two-dimensional soil slope as an example,considering the multi-point input to explore seismic response analysis,compare the single-point seismic input and the multi-point input so as to provide reference for the seismic design of the slope.The results show that multi-point input is safer and more practical than single point input in seismic design. |

| Keywords: | seismic response analysis single-point input multi-point input safety factor |
