场地位于德阳市区,地貌上位于成都平原东北部的石亭江二级阶地。拟建基坑呈矩形,长×宽约为80.7m×47.3m,基坑深度为7.8m-8.9m。由于该基坑位于市中心,四周邻建筑物,且距围墙很近。基于以上原因考虑,基坑支护方案拟采用排桩+锚索进行支护。经过后期施工监测结果显示,周边建筑物没有出现明显可见的裂缝等变形现象,方案在排桩及锚索的尺寸、配筋等方面还有进一步优化的空间,对本地区类似的工程可提供一定的借鉴作用。
The venue is located in Deyang City, the topography is located in the northeast of Chengdu Plain Shiteng River two terrace. The proposed foundation pit has a rectangular shape with a length and width of about 80.7m × 47.3m and a pit depth of 7.8m-8.9m. Since the foundation pit is located in the city center, it is surrounded by buildings and close to the fence. Based on the above reasons, the foundation pit supporting plan is to use the piles + anchor cables for support. After the late construction monitoring results show that there is no visible deformation of the surrounding buildings and other deformation phenomena, the program in the piles and anchor cable size, reinforcement and other aspects of further optimization of the space for similar projects in the region can provide a certain amount of Learn from.
