摘要
以北京—承德高速公路某隧道工程实践为研究背景,在隧道围岩动态地质跟踪调查的基础上,利用常规的围岩位移监测、应力监测以及现场点荷载试验,可及时得到施工过程中围岩变化的综合信息。围岩位移与应力等监测信息为隧道信息化设计和施工提供了依据,是隧道信息化施工、设计的重要手段,对山区高速公路隧道的设计与施工具有一定的参考意义。
Taking the tunnel engineering practice from Beijing to Chengde as an example, based on dynamic geologic research of tunnel wall rock, synthetical and dynamic information of wall rock has been obtained by routine wall rock deformation monitoring and loading test of points. The monitoring information such as displacement and stress of wall rock provides the basis for design and construction, which is an important method and has certain value of reference for the design and construction of the freeway tunnel in mountain area.
