| 摘 要： | 以一座用矿山法施工的水下浅埋软岩公路隧道为工程背景,基于现场实测数据,分析了施作拱墙二衬对初期支护受力性状的影响以及拱墙二衬本身的受力特性.研究结果表明:与浇注拱墙二衬混凝土的前一天相比,浇注完拱墙二衬混凝土后第20d,初期支护的局部锚杆轴力和局部型钢拱架应力明显减小,说明施作拱墙二衬能分担初期支护承受的部分围岩荷载;...

| Abstract: | Taking a shallow,soft rock and underwater road tunnel by the mining method as the project background,based on the measured data,the effects of the arch wall secondary lining construction on the mechanics characters of the primary support are studied,and the mechanics characters of the arch wall secondary lining are analyzed.The results show that the arch wall secondary lining can share the partial surrounding rock pressure,which makes local inner force of the anchor and local stress of the section steel fra... |
