摘要
在对比分析3种围岩分类和6个数学与力学模型成果之后,认为在含有泥化夹层多裂隙的层状围岩中,进行大跨度、深开挖的围岩稳定性分析工作时,进行必要的围岩分类,藉以查清围岩稳定性的普通条件,并发挥不连续介质模型、块体稳定分析、新奥法现场分析等方法的互补作用,可以高质量地进行支护系统设计。
After three kinds of adjoining rock classifications and the results of six mathematical and mechanical models were compared and analyzed, it is believed that when adjoining rock stability analysis of large span and deep excavation in fissured stratiform rock with mud layers was carried out, the adjoining rock shall be classified in order to find out ordinary conditions of adjoining rock stability, and to utilize the complementary effects of disconnected medium model, block stability analysis,and New Austrian Tunnelling Method. Thus high-Quality supporting system can be designed.
