公路隧道建设中安全监测预报的应用

Application of safety monitoring and prediction in road tunnel construction

由于隧道围岩的复杂性和不可见性 ,为尽量避免意外的情况发生 ,在施工的同时有必要采用超前地质预报结合常规围岩变形监测等多种探查手段。文章结合有关的实际工程 ,阐述了多种安全监测方法在公路隧道的综合应用 ,并将现场观察、现场地质调查、现场监控量测所得到的信息进行综合分析 ,进一步加深了隧道的“信息化设计和施工”概念 。

Accounting for the complexity and invisibility of the tunnel rocks and to avoid accident to the utmost, multi-exploring measures of advance geology prediction incorporating the normal monitoring of rock deformation should be adopted during construction. This paper introduces the comprehensive application of multiple safety monitoring methods in road tunnels together with some relevant case studies. The comprehensive analyses of the information obtained by in-situ observation, in-situ geology survey, monitoring and measuring are performed as well. All of them enrich the conception of the 'information design and construction' for tunnels, and will be helpful to the subsequent tunnel projects.
