摘　　要：顶管施工测量是顶管施工技术中重要的组成部分,其目的是实时测量顶管机的空间位置,指导顶管机沿设计轴线开挖,直至顺利贯通。以上海某污水排管工程为背景,结合项目大直径、长距离曲线顶管的特点,从地面控制测量、顶管施工导墙测量等方面阐述了顶管施工测量关键技术,验证了该技术的可行性,保证了顶管施工质量。Pipe jacking construction measurement is an important component of pipe jacking construction technology,which aims to measure the spatial position of the top pipe machine in real-time,guide the excavation of the top pipe machine along the design axis,and ensure smooth penetration.Taking a a sewage discharge pipeproject in Shanghai as the background,combing with the characteristics of large-diameter and long-distance curved pipe jacking of the project,the paper introduces critical pipe jacking measurement techniques from aspects of ground control survey,pipe jacking construction and guidance survey,testifies its feasibility and guarantees the pipe jacking construction quality as well.
