摘　　要：东花园隧道沉降测量点的布置及沉降观测要点,对隧道施工过程及后期运行的安全性有很大影响。结合东花园隧道实际情况,根据沉降测量精度和变形监测网技术的要求,分析了沉降测量布置以及具体观测的要点。分析表明,东花园隧道为客运专线隧道工程,地质条件复杂,将沉降观测点布设在隧道断面的内壁之上,在隧洞工程施工中将所有埋设的监测点作为整个监测网的基准点,每一区间为一个测段,可形成符合测量路线、用于控制整个沉降监测网便于及时调整的施工方法,更好地保证施工质量和施工安全。The arrangement of subsidence measuring points and settlement observation points of Donghuayuan Tunnel have great influence on the safety of tunnel construction process and later operation.Combined with the actual situation of Donghuayuan Tunnel,according to the requirements of settlement measurement accuracy and deformation monitoring network technology,the settlement measurement arrangement and the main points of specific observation are analyzed.The analysis shows that Donghuayuan Tunnel is a project as passenger dedicated line with complex geological conditions.It is suggested to layout the subsidence observation points on the cross section of the tunnel and to take the inbuilt observation points as the benchmark for the entire network in tunnel construction,with a measurement section in each interval,therefore,to form the subsidence monitoring network conforming to the measuring route.It is convenient to adjust the construction method in time to better ensure the construction quality and construction safety.
