【摘要】 本文根据现有地震地质资料,尤其是近五百年来库区周围的历史地震活动情况,对龙滩水库诱发地震可能造成的环境影响作了初步评价.其结果表明,库坝区存在发生破坏性水库地震的风险,尤其库区周围岩溶的存在,为诱发岩溶塌陷型水库地震创造了条件,对于水库堤坝岸坡的稳定是不利的,对库区周围的环境亦有不利影响.更多还原

【Abstract】 The longtan reservoir induced earthquake environmental impact has been evaluated on the basis of the existing hydrogeology data, especially historical seismicity during the short-term period of five hundred years. The result shows that there is risk to induce destroyed reservoir earthquake. Especially karst is a favourable condition to induce karst collapsing explosion type reservoir earthquake. It is disadvantageous for stable of dykes and dams. There is also disadvaatageous impact to reservoir environment.更多还原
