【摘要】 三峡工程是开发和治理长江的关键性骨干工程。由于大坝坝址地址条件十分优越,地震烈度低,且三峡大坝作了比较深入的抗震研究,因此三峡大坝的抗震是安全的。同时,大坝蓄水监测结果表明,蓄水后库坝区频度和幅值明显增加,但都在预期范围之内。此外,三峡工程的蓄水既不具有触发汶川大地震的条件,而汶川大地震也不具备水库触发地震的特征,三峡水库蓄水与汶川地震无关。更多还原

【Abstract】 Three Gorges Project is the key project to control the Yangtze River.With the dam site of very superior conditions and low-intensity earthquake,Three Gorges Dam’s earthquake resistance is safe.As for its reservoir seismic,the monitoring result during storage period indicated that both the frequency of seismic and its amplitude increase remarkably,but they are in anticipated scope.In addition,impounding of Three Gorges Reservoirs was not provided with the ground for triggering Wenchuan Earthquake,and Wenchuan Earthquake has not possessed the characteristic features of reservoir earthquake,so Wenchuan Earthquake has nothing to do with Three Gorges Dam storage.更多还原
