摘要
本文通过地质构造背景、岩溶条件、光弹模拟实验分析,对洪家渡水库可能存在的诱震条件进行研究。在归纳云贵岩溶地区水库地震诱震条件的基础上,用水库地震类比的方法,对洪家渡水库地震进行预测。研究结果认为,洪家渡水库在蓄水至设计水位的1—5年内可能诱发地震。
Based on the geological setting, karst topography and laboratory analysis of photoelastic simulation, the possibly existed conditions for a reservoir-induced earthquake at Hongjiadu Power Station have been studied in this paper. According to the available seismogenic conditions for reservoir-induced earthquakes in the karst areas in Yunnan and Guizhou, a prediction has been made for the induced earthquake at Hongjiadu reservoir by a comparison method. The obtained result indicates that, an induced earthquake might probably occur in 1-5 years at Hongjiadu reservoir after its storage reaches the designed water level.
