随着三峡工程建设,三期移民工作正紧张的进行,由于移民安置的需要,在秭归形成了高切坡,高切坡的稳定与否直接影响着边坡附近居民的生命财产安全和公路的正常运营。本文分析了秭归某边坡的地质条件,在定性定量评价高边坡稳定性的基础上,进行了该高边坡的加固设计。该高边坡据其稳定性可分为两个子区,根据其特点分别采用抗滑锚杆、系统锚喷的治理措施。
With the construction of the Three Gorges Project, the work of the third phase of resettlement is undergoing intense work. Due to the need of resettlement, the high cut slope is formed in Zigui and the stability of the high cut slope directly affects the life and property safety of residents nearby the slope and the road normal operation. In this paper, the geological conditions of a slope in Zigui have been analyzed. Based on the qualitative and quantitative evaluation of the stability of the high slope, the reinforcement design of the high slope has been carried out. According to its stability, the high slope can be divided into two sub-zones. According to its characteristics, anti-skid bolts and system anchor spray control measures are respectively adopted.
