摘　　要：近年来,我国公路和铁路迅速发展,其在穿越山岭地段时易形成浅埋偏压隧道,浅埋偏压隧道的围岩受力特性复杂,导致洞口处易发生围岩坍塌现象。针对浅埋偏压隧道的围岩稳定性问题,文中总结了常用的理论分析和规范计算方法,探讨了围岩压力计算及破坏模式分析的重要性,并进一步展望了未来的研究方向。In recent years,rapid development of highways and railways has been witnessed in China.When passing through mountainous are-as,shallow-buried and biased-pressure tunnels are prone to form,leading to complex stress characteristics of surrounding rocks and the occur-rence of rock collapse at the tunnel entrance.In response to the stability issues of surrounding rocks in shallow-buried and biased-pressure tunnels,this paper summarizes commonly used theoretical analysis and standard calculation methods.It discusses the importance of calculating surrounding rock pressure and analyzing failure modes,as well as provides a further outlook on future research directions.
