摘要
四川省九寨沟至绵阳高速公路白马隧道为深埋(最大埋深1092m)特长(左线长13013m,右线长13000m)隧道,工程地质条件复杂,围岩分级、岩爆、大变形、涌突水、瓦斯、地温等主要工程地质问题对设计及施工潜在影响极大,文章对这些重大工程地质问题进行了分析评价,并在施工中如何防治进行了探讨。
The Baima Tunnel of Jiuzhaigou to Mianyang Expressway in Sichuan Province is a deep buried tunnel(the maximum buried depth is 1,092 m, the length of the left line is 13,013 m, the length of the right line is 13,000 m), and the engineering geological conditions are complex. The main engineering geological problems, such as surrounding rock classification, rock burst, large deformation, water inrush, gas, ground temperature and so on, have great influence on the design and construction. These important engineering geological problems are analyzed and evaluated in this paper, and how to prevent and cure in the construction is discussed.
