 通省隧道衬砌支护及施工组织设计

摘要
我国经济的高速发展，使得人们对交通设施建设的标准也越来越来高，在道路的修建中也越来越来重视行车的舒适性和环保，同时也要求提高其抵抗灾害的能力。因此，为了顺应地形减少对环境的破坏满足线形要求，保证行车的安全经济，本设计根据湖北省十堰市夷陵地区的水文地质条件，选定隧道施工方案。
在设计中，主要进行了隧道的结构、防排水及施工组织设计。首先是各种隧道工程施工方法简介，然后进行合理的隧道几何设计和结构设计计算，并且通过计算分析说明其支护结构的合理性；防排水方面，是在满足隧道适用性以及衬砌结构、路面、设备耐久性条件下，选择合适的防排水材料和设施以及设计防排水系统；施工组织设计中主要安排了监控量测、施工进度安排防排水等，并介绍了具体施工方法及其详细的施作过程。

Structure and construction organization design of tongsheng tunnel LINING

ABSTRACT

 The rapid development of China's economy, makes transport facilities construction standards and more to high, built of the road is more and more to pay attention to in the comfort and environmental protection, but also requires improving its ability to resist disasters. Therefore, in order to follow the terrain to reduce environmental damage meet alignment requirements, ensuring safe economic. In the graduation design, the tunneling method and supporting structure are designed based on the hydrogeological condition of Yiling district located in Shiyan city in Hubei Province.
In the design of the tunnel structure, drainage and construction organization design. First is the Introduction to the construction method of Tunnel Engineering, determine the entrance location, and then make reasonable tunnel geometry design and structure design, analysis and its support structure of rationality; Waterproof and drainage, is to meet tunnel applicability and lining structure and the durability of pavement and equipment conditions, Choice of drainage materials and facilities against the right and the design of waterproof and drainage system ; coordinate major arranged supervision, construction schedule and drainage, and so on, and describes specific construction methods and detailed procedures for the application.
