边坡稳定分析中加速度临界滑动面研究
STUDY ON CRITICAL SLIP SURFACE OF ACCELERATION IN SLOPE STABILITY ANALYSIS
摘要
Abstract
The maximum acceleration can also be used to evaluate the stability of slopes.It has been found that the correlation between the safety factor and the acceleration is more significant when cohesion has smaller weight in shear strength of the soil.In this paper,the correlation between the critical slip surfaces of acceleration and safety factor are further investigated.Results show that for slopes with the slope angle α≥45°,the critical slip surface of acceleration is close to that of safety factor when ξ<0.1 .For reinforced slopes,smaller safety factors are located near the end of the reinforcement when the reinforcement is short.While the location will not change when the reinforcement is long enough.However, the bigger accelerations are always located near the end of the reinforcement,the mechanism of which need further investigation.关键词
