摘要
某大开挖河道在施工过程中发生了滑坡,通过对地质条件、施工方法等方面的深入分析,得出滑坡产生的原因:(1)施工扰动(触变性)。(2)施工期降雨频繁,水位反复涨落。(3)工程地下水位居高不下。(4)施工组织不尽合理。结合工程实际情况,提出了应急处理措施及加固方案。本案例总结,可为其他类似工程提供经验和参考。
A large excavation of River landslide occurred in the construction process, through in-depth analysis of geological conditions, construction methods, obtained the causes of landslide： （1） The construction disturbance （thixotropy） ; （2） During the construction of the rainfall is frequent, the water level fluctuation repeatedly; （3） Engineering underground water level is high; （4） Construction organization is not reasonable. Combined with the actual situation of the project, proposed the emergency measures and reinforcement schemes. Summary of experiences and lessons in this case, can provide experience and reference for other similar projects.
