该小区地点位于宜宾市旧州组团岷江北路以东,总征地面积约为40 896m2,建设用地面积约为37 010m2,拟建房屋5栋,拟入住居民5 000余人。由于建筑区域后方存在一个高于65～105m,长约300m的危岩崩塌区,会影响到建筑小区房屋建筑安全和居民生命财产安全。在基于对本地区的工程地质条件和危岩控制结构面的调查,阐述了危岩变形破坏的机制和模式,并结合相应的稳定性评价给出相应的防治措施。
The plot is located in the east of Minjiang North Road, Jiuzhou, Yibin, with a total land acquisition area of 40 896m2 and a land area of 37 010m2 for construction purposes. It plans to build 5 houses and plan to admit more than 5,000 residents. Since there is a dangerous rock collapse area higher than 65 ~ 105m and a length of 300m behind the construction area, it will affect the building construction safety and the life and property safety of the residential area. Based on the investigation of engineering geological conditions and dangerous rock control structure in this area, the mechanism and mode of deformation and failure of rock are expounded, and the corresponding control measures are given with the corresponding stability evaluation.
