基于实测数据的盾构掘进对地表及建筑物的影响研究

Study on the Influence of Shield Tunneling on Surface and Buildings Based on Measured Data

依托福州地铁2号线金祥站—祥坂站盾构区间,通过分析大量的地表和建筑物监测数据,得到福州软土地层变形和建筑物沉降规律。在研究水土压力和注浆参数基础上,合理设定盾构施工参数,达到控制地表变形的目的。

Ground settlement around tunnel excavation was monitored for Jinxiang station to Xiangban station in Fuzhou Subway Line 2. Mass of measured data was analyzed systematically. The parameters of slurry balance shield,water and earth pressure and grouting parameters were setted for controlling groud surface movement and stratum deformation to satisfy buildings protection.
