摘要
在常张高速公路试验路段边坡稳定性影响因素确定中,采用正交试验方法对坡面角、裂隙饱水系数、岩层走向和路线夹角、岩层倾角、边坡高度等主要因素对边坡稳定性的敏感性作一分析,得到弱风化页岩边坡稳定的一些初步规律,可为边坡开挖设计和加固方案优化提供重要依据。
During the confirmation of safety coefficient influencing factors of Changzhou-Zhangjiajie freeway slope stability, five major factors, such as the influence of angle of slope, water-saturation factor of jointed rock, angle between strikes of route and strata for dip slope, dip angle of rock stratum, height of slope on slope stability are proposed, and the primary rule of slightly weathered shale slope stability is obtained. It will provide theoretical basis for slope excavation and reinforcement schemes optimization.
