SITE MONITORING AND ANALYSIS OF NON-SYMMETRICAL MULTI-ARCH HIGHWAY TUNNEL
不对称连拱隧道现场监测与分析研究

The contents,technique,and method of monitoring in Mazhaiding non-symmetrical multi-arch tunnel constructed by application of NATM are presented. Based on the measured data,the deformation and stress properties of surrounding rocks and supporting system are analyzed. The in-time information is applied to guide tunnel construction and optimize the supporting system,and the monitoring results are discussed. The experience and data presented in the paper can be refereed in the design,construction and research of similar tunnel.
