摘要
杭州地铁建设过程中,地铁1、4线4条隧道先后在富水地层中近距离侧穿火车东站东广场2、3层地下室工程桩。为保护工程桩安全,在盾构侧穿期间进行了大规模的桩身钢筋应力与测斜原位监测,以控制施工参数,指导盾构施工。本文就所开展的监测内容与成果进行分析总结。
The left and right tunnels of metro line 1 and line 4 in Hangzhou pass laterally and nearlybored cast- in- place pile foundations of 2 or 3 floor basements of the Square east of Hang ZhouRailway Station East in muddy and silt stratum. While the tunnels were constructed , the monitoring ofbar stresses and lateral displacement of bored-in-place-piles were carried out to control the speed ofthe tunnel boring. This paper describes and analyzes the monitored results of bar stresses and lateraldisplacements of the piles.
