摘要
针对软弱围岩大跨度地下洞室的复杂受力特征,采用一种比较简便的锚喷支护近似计算方法,即多点支承连续板法分析了京珠高速公路隧道锚喷支护参数,取得了满意的结果。
Based on the complicated properties of soft rock tunnel with large-span dimension,a simple rock bolt and concrete method,namely multi-supporting sheet method,is provided in this paper.Furthermore,the rock bolt and concrete parameters for tunnel supporting system are also analyzed by using this method and the results are well in agreement with real project.
