公路隧道围岩变形破裂类型与等级的判定

Judging of the deformation-cracking type and grade about surrounding rock of highway tunnel

详细阐述了公路隧道施工过程中 ,主要围岩变形破裂 (诸如塌方、大变形、岩溶型涌水涌泥砂、岩爆等 )类型、等级的判定方法和依据 ,这对信息化施工和及时采取相应针对性工程防治措施等均具有重要的理论与实践指导意义 .

This paper elaborates the judging methods and bases about surrounding rock deformation crocking type and grade (i.e.collapse large deformation, gushing water mud sand which have something with the carbonatite predissolution actions, rockburst etc.) in the construction process of highway tunnel.The research results have important theoretical and practical significance to the informational construction and adopting advisable cure engineering measures in times.
