龙潭塆公路隧道初步设计
摘要
随着我国交通基础设施建设的快速发展与不断深入,以及“一带一路”建设的不断推进。隧道建设已经成为公路系统中的重要组成部分。它对优化道路线形、缩短公路里程有着重大影响;同时对促进周边地区环境保护、经济发展及国防建设也具有长远影响。
龙潭塆公路隧道位于十天高速(湖北十堰至甘肃天水),汉中东段。是我国建设的最长的横向快速陆上交通通道,它的修建对我国高速公路网及陕西省公路网建设有重大意义。伴随着我国交通基础设施建设的不断推进,隧道工程俨然已经成为我国公路系统中一条非常重要的分支。
隧道选线时综合考虑了地形地质情况,在衬砌计算中,考虑弹性反力的存在,隧道规划和设计过程中遵循充分发挥隧道功能,安全经济的建设隧道的基本原则,完成整个隧道的初步设计。龙潭塆公路隧道起止桩号K2+50~K3+650,全长1600m,为单面坡道,%。隧道衬砌采用三心圆曲墙式衬砌。洞门采用翼墙式洞门,材料为M10水泥砂浆砌片石。通风经过计算采用SDS--6P-6-18°带1D消声器型射流风机,共9台按单排布置。照明分为入口段,过渡段,中间段,出口和紧急停车带五部分,本设计合理。

Abstract
With the rapid development and constant deepening of the transportation infrastructure construction in China, and continuous promotion of “The Belt and Road”, the tunnel construction has e an important part of the highway system. It has a significant impact on optimizing road alignment and shortening highway mileage, and it also has a long-term impact on environmental protection, economic development and national defense construction of surrounding regions.
Located in Shitian expressway from Hubei Shiyan to Gansu Tianshui, the east part of Hanzhong, Longtanwan Highway Tunnel is the longest horizontal and rapid land transportation channel built in China. Its construction has great significances to the work in our country and the construction of the work in Shaanxi. With the continuous development of transportation infrastructure construction, the tunnel project has e a very important branch of highway system in China.
Tunnel line considering topographical and geological conditions, in the lining of the calculation, consider the elastic force presence, tunnel planning and designing process to follow and give full play to function of basic principles of the construction of tunnel, tunnel safety ec
