摘要
广州市RJ-1地铁上盖基坑围护结构采用地下连续墙及密排的人工挖孔桩作支护,内设一层混凝土支撑的支护方案。通过对该基坑挡土桩及地下连续墙水平位移监测(测斜)、支撑轴力监测、地下水水位观测、角点桩水平位移观测以及周围建(构)筑物沉降观测,确保了基坑施工安全,并对监测结果进行了分析研究。
Underground diaphragm wall and retaining piles with concrete interior support are combined to form the retaining structure of the foundation pit of RJ - 1 subway Upper Cover. Through the monitoring program comprising horizontal displacement monitoring of underground diaphragm wall and retaining piles, inner supporting force monitoring, underground water level monitoring, horizontal displacement monitoring of retaining pile in comer and settlement monitoring of surrounding buildings, the excavation safety is guaranteed. The monitoring results are analysed.
