根据衬砌结构有限元分析方法及公路隧道设计规范 ,对京珠高速公路坪石隧道S2～S4型支护参数进行设计验算 ,并结合新奥法施工监控量测数据 ,对支护参数进行了对比分析
According to the finite element analysis method of lining structure and the design code of highway tunnel, the parameters of S2 ~ S4 support of Pingshi tunnel on Beijing-Zhuhai Expressway are designed and calculated. Combined with the monitoring data of construction of Xin’ao Method, the support parameters are compared analysis
