When tunnel construction develops to surrounding mountainous areas, tunnel portal presents the topographic characteristics of “high, steep, and slant” and geological characteristics of kinds of hugely thick colluvial or residual slope, and the health condition of the deformable body on front slope beside tunnel portal has a great influence on tunnel construction and operation. Tunnel portal has suffered from many disasters, and it is urgent to study and solve the engineering problem on how to diagnose the health condition of front slope beside tunnel portal quickly and accurately. Based on the tunnel of Jianquan village, this paper uses PS-INSAR technique for the first time to analyze and diagnose the health condition of the deformable body on front slope beside mountain tunnel portal at the construction stage and operation stage, so as to provide early warnings to unstable deformable body at tunnel portal and provide strong bases for the treatment of unstable deformable body. Therefore, PS-INSAR technique promotes the health monitoring method for deformable body on front slope beside mountain tunnel portal to a higher level.

PS-INSAR技术在山隧洞口前坡变形体健康诊断中的应用

当隧道建设向周围山区发展时，隧道入口呈现出“高，陡，倾斜”的地形特征和各种厚厚的坡度或残余坡度的地质特征，以及隧道旁前坡的可变形体的健康状况门户对隧道的建设和运营影响很大。隧道门户遭受了许多灾难，因此迫切需要研究和解决如何快速，准确地诊断隧道门户旁前坡健康状况的工程问题。本文以剑泉村隧道为研究对象，首次采用PS-INSAR技术对山隧道洞口施工前和运营期前坡可变形体的健康状况进行分析和诊断，为隧道门口不稳定形变体提供预警，为不稳定形变体的处理提供坚实的依据。因此，PS-INSAR技术将山隧道入口旁前坡可变形体的健康监测方法提升到更高的水平。
