摘要
从隧道沉降、接头差异变形、节段张合量、环境温度监测等方面,介绍了港珠澳大桥沉管隧道施工监测系统的建立及运行,并对差异变形及沉降监测数据进行了分析,验证了监测系统的可靠性。本套系统的建立保障了沉管隧道施工安全,并为后续管节施工提供依据。
This paper presents the establishment and operation of the construction monitoring system of immersed tunnel of Hongkong-Zhuhai-Macao Bridge from the aspects of tunnel settlement, deformation of tunnel joint, opening and compressed value of tunnel, environmental temperature, etc., and analyzes the deformation of tunnel joint and settlement which proves the reliability of the monitoring system. Through the establishment of the system to assure the construction safety and the system provides a basis for the subsequent construction of immersed tunnels.
