摘　　要：介绍了浅埋、大跨度、双洞八车道小净距公路隧道的初步设计方案,有限元计算表明水平对拉锚杆和系统锚杆的设置有利于抑制中柱塑性区的交叉连通及拱顶塑性区与地面的连通,所得结论对类似隧道设计和施工有参考价值。The design described. FEM calculation are helpful for controlling Conclusions can be referred outline of shallow embedding long-span neighbourhood highway tunnel is based on this tunnel shows horizontal prestressed bolts and regular rock bolts the development of plastic-yielding zone of inner rocks and roof rocks. in other tunnel engineering.
