摘要
本文结合富强路2#框架桥的工程实例介绍了顶进法施工过程当中对现场各种项目的监测。主要监测内容包括桩轴力监测、涵顶挠度监测、水位监测和地表沉降监测。其中,对基坑周边地表沉降监测是通过典型断面的实测数据来观测其沉降情况;其它的监测项目是选取典型的测点进行数据分析与研究。结果表明,各项目的监测有效控制了顶进过程中的线路方向和安全施工。
Based on the project of No.2 frame bridge on Fuqiang road,this paper introduces all monitoring items during jacking process. The main monitoring items include pile axial force,top deflection of box bridge,underground water level and ground surface settlement. The monitor of settlement around the pit is mainly analyzed through the typical profile, other monitoring items are also carried out by selecting some typical points to analyze. Study results show that the monitoring of all items effectively control the jacking direction and safe construction.
