| 摘 要： | 本文通过实验确定了砂岩在干燥、饱水、有孔隙压三种情况下的摩尔破裂准则线(摩尔包络线);定量地说明了砂岩的弱化,并以此阐明水库地震的发生过程及其特点,指出了以往应力分析中的疏漏,指出含水岩石的弱化是水库地震等水诱发地震的首要的影响因素。

| Abstract: | This paper has established three Mohr's Crack Criterion curves of sandstone under the conditions of dryness, weteness and 300 bars of pore pressure, with the last two being water-saturated, illustrated the weakening of the sandstone quantitively, and with this explained the process and characters of the reservoir earthquake, corrected the oversights and omissions of the conventional stress analysis, pointed out that the weakening of water-saturated rocks is the main factor of the reservoir earthquake and other water-induced earthquakes. |
