本文讨论了地震小区划中的地震工程地质方法。指出,这种方法将工程地质与地震工程结合在一起,可以有效地解决场地评价问题,特别是评价地基失效的可能性和程度。在地震小区划中,这种方法不仅不应受到轻视,而且应当将它和理论分析方法结合在一起,从宏观和理论两个方面全面解决地震小区划中的问题。笔者在西安市地震小区划的第一阶段中应用了这种方法。 This paper discusses the seismic engineering geology in the subregion of the earthquake. It is pointed out that this method combines engineering geology and seismic engineering, which can effectively solve the problem of site evaluation, especially the possibility and degree of evaluating the foundation failure. In the subdivision of the earthquake, this method should not only be underestimated, but also be combined with the theoretical analysis method to comprehensively solve the problems in the subdivision of the earthquake from macroscopic and theoretical aspects. The author applied this method in the first phase of the earthquake zoning in Xi’an.
