摘要
徐家梁子隧道是西攀高速公路的一个重要控制点,根据该隧道围岩岩性特征、岩体强度、岩体结构特征、风化程度、结构面发育分布特征及岩体完整性等特征,对其进行了围岩分类,其结果对隧道施工和衬砌类型的选择提供了依据。
Xujialiangzi tunnel is an important control point, after considering synthetically the rock＇ s character, rock mass＇ s strength and structure character, disintegrated degree, the distribution character of classification structural surface development and integrality of rock mass, the surrounding rock of tunnel is classified, the result is the basis in construction of the tunnel and selection the type of lining.
