摘要
基于传统剩余推力法,提出了新的抗滑桩优化方法。以位于凉山彝族自治州某县城南的滑坡体为例,说明了主要治理方法。采用剩余推力法和新的抗滑桩优化方对该滑坡体天然状态工况进行了稳定分析。结果显示,在设计安全系数为1.15的情况下,该滑坡处于临滑状态,因此,须采取相应的加固措施,最后推荐了抗滑桩设计方案,已在凉山州某县城滑坡工程中成功实施。
A new anti-slide pile optimization method is presented based on the conventional residual thrust method. Take the slope located in south of the Meigu county for an example, it explains the main treatment methed. It analyses the slope stability in the state of natural condition with the residual thrust method and new anti-slide pile optimization method. The result shows that the slope is at near the slippery condition when the designed safety coefficient is 1.15. Therefore, the corresponding reinforcement measure should be taken. At last, the anti-slippery pile design proposal is recommended, and it is already implemented in the slope of Meigu successfully.
