摘要

Semicircular depression terrain is a very common terrain in civil engineering, and terrain has a very important influence on the amplification of seismic action. Among them, the depth‐to‐width ratio of semicircular depression terrain has a non‐negligible impact on surface displacement. In this paper, the pulse wave is used as the input seismic shock for analysis, and the effects of two semicircular depression terrains with different depth and aspect ratios on seismic responses are compared, so as to derive the influence of the depth and aspect ratio of different semicircular depression terrains on surface reactions under the same seismic wave, and the conclusions obtained are presented in this paper in combination with graphical analysis.
