通省隧道襯砌支護(hù)及施工組織設(shè)計

摘要
我國經(jīng)濟(jì)的高速發(fā)展，使得人們對交通設(shè)施建設(shè)的標(biāo)準(zhǔn)也越來越來高，在道路的修建中也越來越來重視行車的舒適性和環(huán)保，同時也要求提高其抵抗災(zāi)害的能力。因此，為了順應(yīng)地形減少對環(huán)境的破壞滿足線形要求，保證行車的安全經(jīng)濟(jì)，本設(shè)計根據(jù)湖北省十堰市夷陵地區(qū)的水文地質(zhì)條件，選定隧道施工方案。
在設(shè)計中，主要進(jìn)行了隧道的結(jié)構(gòu)、防排水及施工組織設(shè)計。首先是各種隧道工程施工方法簡介，然后進(jìn)行合理的隧道幾何設(shè)計和結(jié)構(gòu)設(shè)計計算，并且通過計算分析說明其支護(hù)結(jié)構(gòu)的合理性；防排水方面，是在滿足隧道適用性以及襯砌結(jié)構(gòu)、路面、設(shè)備耐久性條件下，選擇合適的防排水材料和設(shè)施以及設(shè)計防排水系統(tǒng)；施工組織設(shè)計中主要安排了監(jiān)控量測、施工進(jìn)度安排防排水等，并介紹了具體施工方法及其詳細(xì)的施作過程。

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.

KEYWORDS: Tunneling engineering；Lining；Structure; Waterproof  and drainage ；Construction organization
