| 中文摘要: |
| 本文针对永吉高速黑潭坪特殊的滑坡现象,结合该区域的具体情况,采取现场调研、数值分析和理论计算等多种手段相结合的方法对滑坡进行稳定性分析,并做出了详细的治理方案.结果表明:该滑坡为工程开挖坡脚引发的牵引式滑坡；坡体变形主要原因是坡体岩土工程性质不良,加上工程开挖而切削坡脚和降雨入渗导致边坡岩土体软化,降低了坡体稳定性.根据边坡的稳定状况及其工程地质条件,提出三种治理方案,并分别阐述了优缺点及适用情形,考虑施工难度及工程造价,建议采用上部抗滑桩+底部桩板墙治理方案加固. |

| Aiming at special landslide phenomenon at Heitaiping,landslide stability is analyzed by field research.Numerical analysis,theoretical calculation,and the concrete reinforcement schemes are proposed.The results show that the landslide is retrogressive landslide induced by engineering excavation,and the primary cause of the landslide is bad geotechnical engineering properties with engineering excavation and rainfall infiltration.According to steady-state situation and engineering geological conditions,three kinds of treatment schemes were proposed with their advantages and disadvantages attached.Considering the construction condition and budget,the treatment scheme integrating upper anti-slide pile method and bottom slab-pile wall method can meet the construction requirements. |
