Field studies by squeezing rock deformation have shown that large deformation slips can occurs in tunnels in squeezing rock, the tunnels may be partially or completely broken. This article proposed two schemes for controlling the deformation of squeezing rock, which are “resistance combine release” Scheme 1 and “strong support” Scheme 2, the deformation characteristics and deformation mechanism of squeezing rock is researched by Zhongyi Tunnel. The results show that Scheme 2 is superior to Scheme 1 in terms of deformation rate, cumulative deformation, and monthly construction footage. Research results can provide a reference for similar projects.

挤岩隧道大变形控制技术及其应用研究

挤压岩变形现场研究表明，挤压岩隧道内可发生大变形滑移，隧道可能部分或全部破裂。本文提出了两种控制挤压岩体变形的方案，即“抗阻联合释放”方案一和“强支护”方案二，并以忠义隧道为研究对象，对挤压岩体的变形特征和变形机制进行了研究。结果表明，方案2在变形率、累计变形、月施工进尺等方面均优于方案1。研究成果可为类似项目提供参考。
