结合某客运专线隧道工程实践，以斜井—进口段隧道变形为分析对象，详细介绍了该区段隧道施工方案和监测布置。根据该区域内隧道变形分布特点，研究了不同监测断面拱顶下沉和收敛位移随斜井和进口端掌子面进展的变化特点。根据现场监测反映的进口和斜井贯通面附近变形速率和变形值极大的情况，提出了必须要加强该范围内隧道变形监测与控制。

Based on tunnel pructice of one passenger dedicated line,tunnel deformation of inclined shaft to entrance zone is studied as the analysis obj ect,the construction scheme and monitoring arrangement of tunnel deformation are summarized in details. The tunnel deformation of that zone is summarized.The behaviors of crown settlement and the change of convergence displacement with the excavation progress of inclined shaft to entrance zone are investigated.The monitoring results show that the deforma-tion rate and values of the tunnel section close to the plane is very large.Deformation monitoring of that section and some controlling measures should be strengthened.
