摘要
通过重庆长寿地区大洪河水电站、狮子滩水电站、上硐水电站、回龙寨水电站及桃花溪水电站库区受库水长期浸泡的饱水岩样和岩性与其相同但未受库水影响的干岩样抗压强度来求导岩石经长期浸泡后的软化系数以及软化系数随时间的变化规律。试验结果表明，经过几十年库水浸泡后的泥岩的软化系数较实验室测得的软化系数降低20％～30％，显示重庆长寿县地区岩石水-岩作用具有时效性特点。
Based on the experimental study on softening efficient and changing features of dry mudstone sample and saturated one by reservoir water soaking from Dahonghe hydropower station, Sizitan hydropower station, Shangdong hydropower station, Huilongzhai hydropower station and Taohuaxi hydropower station, Changshou region, the experimental results show the softening efficient can reduce 20%-30% after tens of reservoir water soaking, there is a time effect of rock--water interaction in the region.
