监控量测是新奥法施工的核心,是监视围岩稳定性,检验设计与施工是否正确合理及安全的重要手段。本文根据重庆市云阳至万州高速公路观音庙隧道新奥法施工情况,通过对隧道监控量测数据的分析,对围岩变形特性进行总结,同时并对影响围岩稳定性的主要因素进行了研究分析,得出切实可行的数据和结论来指导施工,如不同围岩类别二次衬砌的施作时间等。希望通过对观音庙隧道洞身段围岩的总结分析,得出相关问题的结论和建议,对今后的工程实践具有一定的参考价值。
Monitoring measurement is the core of the new Austrian law construction, is to monitor the stability of surrounding rock, test design and construction is an important and reasonable means of security. According to the new Austrian law construction of Guanyinmiao Tunnel from Yunyang to Wanzhou Expressway in Chongqing, the deformation characteristics of the surrounding rock are summarized through the measurement data of tunnel monitoring, and the main factors influencing the stability of surrounding rock are also discussed Research and analysis, come to practical data and conclusions to guide the construction, such as different types of rock around the second lining of the construction time. It is hoped that through the summary and analysis of the surrounding rock of the tunnel body of the Guanyinmiao Tunnel, the conclusion and suggestion of the relevant problems are obtained, which will be of certain reference value to the engineering practice in the future.
