大型碎石堆积层滑坡治理及监测分析

依托保宜高速车峰坪大型碎石堆积层滑坡治理工程，根据现场情况及勘察结果分析斜坡的稳定性，研究开挖后边坡的失稳破坏机理。采用实际位移监测，同时对比Slide数值模拟计算加固后边坡的安全系数，了解斜坡的稳定状态，为后续斜坡治理提供依据。结果显示:施工开挖是斜坡失稳的主要因素，集中降雨是斜坡失稳的诱导性因素，二者叠加作用使得斜坡失稳，采用抗滑桩加固措施有效地增加了边坡的稳定性。

Landslide Control of Large Gravel Accumulative Formation and the Monitoring Analysis

Relying on the landslide control project of large Chefengping gravel accumulative formation along Baokang-Yichang Highway, the slope stability was analyzed according to the site conditions and the survey results so as to study the failure mechanism after excavation. With the actual displacement monitored, simultaneously, compared to the safety factor of the reinforced slope calculated by Slide numerical simulation, the stability of slope was known, providing the basis for the following slope treatment. The result shows that, if the slope fails, excavation is the main factor and concentrated rainfall is the inducement factor, the superposition of both causes the slope failure; with anti-slide piles applied for reinforcement, the stability is enhanced effectively.
