高速公路伙路隧道工程毕业设计.doc

摘要
本设计根据济南市历城区港沟镇南的地质地貌情况,选定隧道方案。隧道全长1229m,在设计中,主要进行了隧道的施工组织、通风、照明、防排水及施工方案等。首先,选定隧道路线,确定洞口位置,然后进行合理的隧道几何设计;通风照明方面,是在满足交通量和运营状况的条件下,通过计算结合施工的便利与否加以调整设计;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。
本设计为济莱高速公路伙路隧道设计,济莱高速公路伙路隧道地处济南市历城区港沟镇境内,是位于山东南济青高速公路济南莱芜段中的第一条长隧道。隧道在济南市历城区港沟镇境内,横穿伙路村与兰峪村之间的伙城山,总长1229m,为单向双车道的高速公路隧道。济莱高速第一合同段中的伙路隧道西起有兰峪村(左幅起点里程LK3+613,右幅起点里程RK3+604),东至伙路村(左幅终点里程LK4+835,右幅起点里程RK4+833)。
,所处围岩等级为Ⅲ、Ⅳ、Ⅴ级;伙路隧道位于低山~中低山丘陵区,属泰山余脉和支脉,山体最高峰海拔标高为 。由规范可知,该隧道属于长隧道,设计水位的洪水频率为百年一遇,隧道的通风和照明设计内容按照行车速度100km/h设计。
本次设计的主要内容包括:隧道横断面、洞门与明洞、衬砌与支护、施工方案、防排水、通风照明等。

Abstract
This design according to the Ji Nan City in Shandong Province village area of geological and geomorphological conditions, selected the bored tunnel approach. 1229m tunnel length. In the design of the tunnel structure, ventilation, lighting, drainage and anization design. First of all, the selected routes, determine the entrance location, and then make reasonable tunnel geometry design and structure design, analysis and its support structure of rationality; ventilation and lighting, is to meet traffic and operation conditions, by calculating bined construction of convenience or not adapted design; coordinate major arranged supervision, construction schedule and drainage, and so on, and describes specific construction methods and detailed procedures for the application.
The design for the Huolu Highway Tunnel Design. It is located in Ji Nan. Its one of central station number is LK3+613 ~ LK4+835,the other part of central station number is RK3+604~ RK4+833。Its length is 1229m;,and the surrounding rockgrade is for Ⅲ、Ⅳ、Ⅴ level; The tunnel ventilation lighting design and content in accordance with the road speed 100km/h design.
The main elements of design include: the tunnel location, portal design and Opencut tunnel design, lining and support the design, construction design, drainage design, lighting design, ventilation design and
