软岩地段隧道初期支护变形侵限及其处治分析

Analysis of Limit Deformation and Treatment of Initial Support of Tunnel in Soft Rock Section

隧道工程建设中初期支护变形侵限是常见施工事故,多数是由于软岩大形变引起的。本文首先针对影响隧道初期支护变形的软岩问题进行了详细分析,其后探讨了软岩地段隧道初期支护变形问题与处治方法,最后围绕陡岩村隧道项目展开论述,以期可供参考。

In the initial stage of the tunnel construction,the limit deformation of the support is a common construction accident,most of which are caused by the large deformation of the soft rock.This paper firstly analyzes the soft rock problems that affect the deformation of the initial support of tunnel,and then discusses the deformation problems and treatment methods of the initial support of tunnel in the soft rock section.Finally,it discusses the Douyancun tunnel project for reference.
