紧邻建筑物崩塌堆积体滑坡治理对策研究
摘要:山体边坡爆破开挖过程中，爆破方法不当，导致坡面形状不规则，坡度不合理，坡面残留大量岩土体，边坡卸荷后，坡肩位置变形大，出现持续性崩塌破坏，其紧邻在建建筑物，直接威胁坡底建筑施工活动安全，根据此类边坡特点及地质构造特性，分析了崩塌堆积体滑坡成因及特点，提出了无空间崩塌堆积体滑坡治理方法，工程实践证明，采用反压护道+护坡桩+柱板墙+锚杆格子梁组合结构治理类似边坡，安全经济，施工方便，支护结构与坡底建筑工序可平行施工，保证了坡底在建建筑施工安全及工期要求，为类似边坡治理提供了借鉴意义。
Abstract:During the blasting excavation of mountain slope,due to improper blasting method,the shape of the slope is irregular and the slope is not reasonable.A large amount of rock mass remains on the slope.After the slope unloading,the deformation of the slope shoulder is large and the sustained collapse and destruction is occurred.It is a directly threat to the safety of construction activities of adjacent building on the slope bottom.According to the characteristics of this kind of slope and the geological structure,the causes and characteristics of the collapse accumulation body landslide was analyzed,and the non-limitation of workspace control method of collapse accumulation body landslide was put forward.It was proved by engineering practice that using the composite structure of back berm+slope protection pile+pillar-plate wall+bolt lattice girder to protect similar slope is safe and economical,and is convenient for construction.Support structure and slope bottom construction process can be parallel conducted,safety requirements and period of slope bottom construction is guaranteed,which provides a reference for similar slope management.
