我国位于世界两大震带之间,具有地震活动频度高、强度大、震源浅等特点。为了降低地震带来的危害、减少地震造成的人员上万,我国岩土工程及相关勘察勘探中加强了对地震效应的要求与规范。通过科学的岩土工程勘察阶段地震效应的评价,提高结构设计抗震设计能力及水平,为满足岩土工程建设要求奠定基础。本文就岩土勘察中的地震效应问题进行了分析与论述。
China is located between the two major earthquake zones in the world and has the characteristics of high seismicity frequency, high intensity and shallow source. In order to reduce the harm caused by the earthquake and reduce tens of thousands of people caused by the earthquake, China’s geotechnical engineering and related survey and exploration have strengthened the requirements and norms for the earthquake effect. Through the scientific geotechnical investigation phase seismic effect evaluation, improve the structural design of seismic design capacity and level, in order to meet the geotechnical engineering requirements laid the foundation. This paper analyzes and discusses the earthquake effect in geotechnical investigation.
