摘要摘 要在这个经济迅猛发展的时代，人们不仅对交通工具的需求越来越大而且对于道路建设的要求也越来越高，在道路保证安全环保的前提下还要要求对经济的发展也要有至关重要的作用。本设计为跑马山二号公路隧道。是由川入藏的必经之地，对缩短川藏通行时间有着举足轻重的作用，隧道全长 2170m。 本次设计中，对隧道进行了衬砌内力的计算以及通风照明的计算，本隧道采用三心圆拱的的形式进行，洞身部分用复合式衬砌的方法以满足工程的需要。该隧道由八个设计内容组成。第一部分为对隧道的地形地貌、地质条件和所处地段进行描述和概括；第二部分为对隧道的一般规定和整体规划的介绍；第三部分为洞门的设计，对相对应的抗倾覆、抗滑等的验算；第四部分和第五部分为隧道衬砌的计算及对对应的验算；第六部分为通风计算；第七部分为照明的计算，最大程度满足使用的舒适性；第八部分为施工组织设计，并对重要的质量、工期、环境等进行要求。关键词：复合式衬砌；洞门设计；通风照明IAbstractAbstractIn this era of rapid economic development, people not only have an increasing demand for transportation, but also have higher and higher requirements for road construction. On the premise of ensuring safety and environmental protection on the road, they must also have economic development. Important role. The original design is the Happy Valley No. 2 highway tunnel. It is an indispensable place for Sichuan to enter Tibet, which plays a significant role in shortening the transit time between Sichuan and Tibet. The total length of the tunnel is 2170m.In this design, the tunnel lining internal force calculation and ventilation lighting calculation are carried out. The tunnel is carried out in the form of a three-center circular arch, and the tunnel body part is compounded by lining to meet the needs of the project.The tunnel consists of eight design elements. The first part is to describe and summarize the topography, geological conditions and location of the tunnel; the second part is to int...
