摘要
以二郎山公路隧道施工过程的工程实践为依据 ,利用常规围岩变形监控量测和围岩变形跟踪监测系统及二次应力场测试 ,获取隧道围岩动态综合信息 ,为围岩分类、大变形预测、岩爆预测、优化二次支护时间及反分析等提供依据 ,是岩土工程信息化设计。
Based on Erlang mountain road tunnel engineering practice,surrounding rock dynamic composite information of highway tunnel was obtained by routine surrounding rock deformation monitoring measurement,surronding rock deformation trace monitoring system and quadratic stress field measure.Dependable data was provided in surrounding rock class,large deformation and rockbust forecast as well as majorizing quadratic bearing time.Surrounding rock deformation is an important method of geotechnical engineering infomation design and construction.
