| 摘 要： | 从隧道围岩的岩体成分、地下水发育情况等方面入手,分析了软岩隧道初期支护变形大的成因,提出采用网构钢架支护体系,并根据老折山隧道试验段的成功经验,认为格栅支护为柔性支护体系易与围岩共同形成承载体,可有效控制围岩变形。

| Abstract: | From the rock composition of tunnel surrounding,groundwater development,etc. ,this article analyzes deformation reasons for initial support in soft rock tunnel,put forwards grille steel supporting system,based on the successful experience of the test section in“Laozhe”mountain tunnel,thinks that grille support is the flexible support system,grille support system and rock easily form the carrier,can effectively control the deformation of surrounding rock. |
