3、系数计算了滑坡的 稳定性系数和推力,并对滑坡的稳定性进行了定量评价。根据“合理经济、工期短、 工程技术可行、 安全可靠管理效果”的设计原则,选择了抗滑桩的处理方案,并进行了 滑坡治理设计。 关键词关键词:滑坡;稳定性;治理设计;抗滑桩滑坡;稳定性;治理设计;抗滑桩 Abstract This design is based on the basis of Qingyuan City landslide related survey data as the basis, then the factors which tampered with the slopes stability were
4、construed, the reasons which caused the landslide were analyzed and the landslides stability was estimated. According to the unbalance thrust transmission coefficient methods principle and supposition,the landslides stability coefficient was calculated. Then the landslides stability was appraised. B
5、ased on the analysis, the treatment measure were advanced. According to the result of the slope stability calculation, the design principle was that the project cost was reasonable, time limit for the project was much less, the technique was possible and the project was simple and easy to construct.
6、 Finally, a revised designing program has been chosen, which included anti-slide pile and drainage works . At last,the slopes designation of remedying engineering was made.
