摘要
软弱风化复合顶板巷道是围岩变形剧烈且顶板易冒落极难维护的一类巷道,文章采用数值模拟的方法,提出了合理的锚杆支护参数,并且成功应用于工程实践。
The entry of composite roof weathered weak rock tunnel deformation is intense and the roof caving easy to extremely and difficult to maintain,the paper used the method of numerical simulation proposed bolting reasonable parameters,and successfully applied to engineering practice.
