摘　　要：随着国家对交通建设投资的不断增加,隧道建设规模也在不断扩大,如何在保证隧道施工安全的基础上,加快施工工期、控制工程成本成为最为关注的问题。该文以德阳市某隧道施工为例,基于现场地质素描、超前地质预报、岩石试验和监控量测结果对原有设计方案进行优化设计,并从施工安全、工程质量、工程进度等方面与原有设计方案进行对比,确定方案合理性,旨在为类似隧道工程开挖方案的优化设计提供参考。With the continuous increase of national investment in traffic construction,the scale of tunnel construction is also expanding.On the basis of ensuring the safety of tunnel construction,how to speed up the construction period and control the project cost has become the most concerned issue.Taking the construction of a tunnel in Deyang City as an example,this paper optimizes the original design scheme based on the results of on-site geological sketch,advance geological prediction,rock test and monitoring measurement and,compared with the original design schemefrom the construction safety,project quality,project progress and other aspects,determines the rationality of the scheme.The purpose of this paper is to provide reference for the optimal design of excavation schemes of similar tunnel projects.
