我国是多地震的国家,断裂构造纵横交错,遍及全国。大的断裂带延长上百上千公里,小的断裂到处可见,常常被怀疑为工程场地稳定性的隐患。自从邢台、海城、唐山等地区发生大地震、并且对一些铁路工程造成危害以后,在铁路新线勘测设计中,活动断裂带的勘测和评价问题,引起更大的重视,成为铁路选线的重要控制因素之一。本文试图应用我国地震 China is a country with many earthquakes, with fault structures criss-crossing the country. Extending a large fault hundreds of thousands of kilometers, small faults can be seen everywhere, often suspected of stability of the project site. Since the occurrence of a major earthquake in Xingtai, Haicheng and Tangshan areas and the detriment of some railway projects, the survey and evaluation of active fault zones in the investigation and design of the new railway line has drawn more attention and become the core of railway alignment One of the important control factors. This article attempts to apply China’s earthquake
