多点输入条件下的土质边坡地震反应

Seismic Response of Soil Slope Based on the Multi-point Input

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.
