随着我国经济的迅猛发展,汽车保有量不断提升,公路隧道车流量越来越大,为了顺应经济的发展,我们设计了越来越多的三车道、大断面公路隧道,为了确保大断面浅埋段隧道施工安全,为设计提供依据,我们对某大断面隧道浅埋段围岩内部位移和锚杆轴力特性的分析。 With the rapid development of economy in our country, the number of vehicles kept increasing and the traffic volume of highway tunnels getting larger and larger. In order to comply with the economic development, we designed more and more three-lane and large-section highway tunnels. In order to ensure large cross-section The construction safety of the buried tunnels provides the basis for the design. The analysis of the internal displacement of the surrounding rock and the axial force characteristics of the anchors in the shallow buried section of a large section tunnel.
