摘　　要：以某工业园区新建道路下穿高速公路项目为依托,进行箱涵顶进过程中的施工监测研究。针对该工程特点,提出了几项减少箱涵顶进阻力和控制沉降位移的措施以及顶进过程监测方案。经现场监测数据结果表明,该箱涵顶进过程箱涵姿态控制较好,对路面的位移和沉降影响较小。Based on the project of a new road crossing expressway in an industrial park,the construction monitoring of box culvert jacking is studied.According to the characteristics of the project,several measures for reducing jacking resistance and controlling settlement displacement of box culvert and monitoring scheme for jacking process are put forward.The field monitoring data show that the attitude control of the box culvert during jacking is good,and the influence on the displacement and settlement of the road surface is small.
