摘要
为解决松软围岩巷道的极不稳定性及寻求新的控制方法,在分析松软围岩变形特征的基础上,提出了强化预支护技术方法,并结合实际工程,获取一些岩性参数,用FLAC进行了4种预支护方案数值模拟和对比分析,认为强化预支护具有最优的特点。
In order to seek for new support means of roadway in loose and soft rock, after analyzing the deformation characteristics of loose and soft surrounding rock, an enhanced pre - support technique is put forward. The some parameters of rock are gained according to the practice engineering. The numerical simulation, comparison and analysis of four kind of pre - support means are carried out by sue of FLAC, the results show that enhanced pre - support technique is optimum for loose and soft surrounding rock of roadway.
