摘要
高速公路隧道工程中,衬砌为重要支护结构,以复合式衬砌较为典型,其有助于改善外层支护受力条件,以免围岩出现失稳、坍塌等状况。论文以高速公路秋山隧道工程为依托,介绍了该工程具体采用的复合式衬砌施工方案,重点围绕其设计要求与施工内容展开探讨,包括初期支护、设置防水隔离层等环节,最终取得了良好的施工效果。
In expressway tunnel engineering,the lining is an important support structure,and the composite lining is a typical one.It helps to improve the stress condition of the outer support,so as to avoid the instability and collapse of surrounding rock.Based on the Qiushan Tunnel Project of Expressway,this paper introduces the construction scheme of compound lining,focuses on its design requirements and construction content,including initial support,setting up waterproof isolation layer and other links,and finally obtains good construction results.
