| 摘 要： | 长江三峡大坝蓄水后,水位将达到175m,而平时水面浪高预计将达到1m,因此波浪对岩质边坡稳定性能的影响已不能忽略。本文通过对含应变弱化介质夹层岩质边坡在波浪作用下的力学分析,提出波浪扰动下位移累积引起的夹层介质弱化和时间累积是影响边坡稳定的主要原因,最后得出考虑波浪作用时间因素的稳定性评价方程。

| Abstract: | After the three gorge large dames of the Changjiang River reservoir water, the water level will reach 175meters, and surface average wave height will reach 1meter high. Therefore the wave action cannot be neglected for the stability of the rock slope. Based on the mechanical analysis of the rock mass slopes with a belt of weak intercalated layer acting on the wave, this paper obtains that the accumulation of deformation which causes layers weakening and time are the main factors lead to the rock mass slope fault, and finally the stability Evaluation equation considering time factor of wave action is established. |
