二十世纪七十年代以前,地下结构抗震设计一直沿用地面结构抗震设计的方法,而地表结构和地下结构大相径庭,地下结构的抗震设计对于地质结构、地下水等的考察应该更加严谨和细致,设计要求更加严格。所以,地面结构抗震设计存在很多局限和不足,明显不适用于地下结构的抗震设计。那么,究竟地下结构抗震设计有哪些方法呢?本文就旨在分析比较以及探究各种设计方法。
Before the 1970s, the seismic design of underground structures always followed the seismic design method of ground structures. However, the surface structures and underground structures were quite different. The seismic design of underground structures should be more rigorous and meticulous for the investigation of geological structures and groundwater. The design requirements More stringent. Therefore, there are many limitations and deficiencies in the seismic design of ground structures, obviously not suitable for the seismic design of underground structures. So, what exactly is the seismic design of underground structures? This paper aims to analyze and explore various design methods.
