摘要
气爆可能为水库诱发地震的一种成因。本文讨论了气爆机理。通过弹性理论分析和能量计算,讨论了它产生的条件,估计了其一般震级。 岩溶区的一些中小水库曾出现过气爆现象。但曾被作为典型气爆成因的乌江渡水库诱发地震却不属于气爆型。
Gas explosions in karst caves might be a cause for reservoir induced seismicity.The occurrence condition and mechanism of gas explosion are discussed and the possible magnitude of induced earthquake is estimated in this paper.Phenomena of gas explosion have been found at the reservoirs in karst area in China. But the induced earthquakes at Wujiangdu reservoir which have been considered as typical gas explosion are not caused by the gas explosion.
