摘　　要：介绍了岩石长期受水作用的弱化机理,特别是水-岩化学作用;对测定岩石软化系数的传统试验进行了分析,发现此法所测得的软化系数无法准确评价岩石长期受水作用时水对岩石的影响程度,并且这影响其在某些工程中的应用价值,最后针对这一问题对传统试验方案提出了优化措施。Introduce the mechanism of rocks subjected to water′ s long-term action, especially the water-rock chemical action. By analyzing the traditional test for measuring rock softening coefficient,found that it couldn′t accurately evaluate the influence of water on rock when the rock was subjected to long-term water effect, and that would affect its application value in some engineering. Finally, the optimization measures for the traditional test were proposed.
