| 摘 要： | 核电厂地震安全性评价中的地震构造法,要求鉴定发震构造和划分地震构造区,在以往实践中,发震构造鉴定往往基于地表活动断裂构造,且表征为线状震源.当存在较强非随机分布的地震活动且难以找到清晰的地表活动断裂构造形迹时,地震构造法就难以合理地表现这些地震的危险性.本文以云南滇中大姚—姚安发震构造鉴定为例,探讨了在地表活动构造形迹不清,中强地震活动性较强的滇中大姚—姚安地区,采用面状发震构造来表征地震危险性的方法,讨论了在地震构造法中采用面状发震构造的必要性、鉴定思路和方法,并建议在今后的核工程地震危险性评价地震构造法中应充分考虑面状发震构造的应用.

| Abstract: | In seismic hazard analysis of nuclear power plant of China there is a need to identify both of seismogenic structures and seismotectonic zones. In the past practice, the identification of the seismogenic structures was often based on the surface active faults and characterization of linear seismic source. In the situation which shows quite strong non-random seismic activity and lacks of the surface active faults, however, it is difficult to evaluation of the seismic hazard reasonably. Taking Dayao - Yao'an seismogenic structure as a case study in this paper, we discuss the need and the possibility to apply the planar seismogenic structure in seismotectonic method. Then we suggest that the planar seismogenic structure should be considered in seismotectonic method of nuclear engineering in future. |
