通渝公路隧道工程设计

Engineering Design of Tongyu Highway Tunnel

通渝隧道目前是重庆最长 ( 4 2 79m)、国内埋深最大 ( 1 2 0 0m)、工程地质条件最复杂(高地应力、岩爆、岩溶、煤层瓦斯 )的单洞双向行驶的长大公路隧道。本文以隧道设计为例 ,详细介绍了隧道在各种不良地质条件下土建结构设计上的措施 ,以及防灾、机电附属工程设计。

Tongyu Tunnel is the longest (4279m) one in Chongqing and the deepest (1200m) in China, it is a single double line long large highway tunnel, where the engineering geological conditions are very complicated (high ground stress, rock burst, karst, coal seam gas). In this paper, taking this tunnel design as an example, the measures for structural design of civil engineering in unfavorable geological conditions and the disaster prevention and electrical and mechanical facility designs are introduced in detail.
