摘要扩大拱脚在大断面软弱地层隧道中能够比较好的控制地层的变形，在既有研究的基础上，进一步对传统的扩大拱脚结构进行改进，提出一种抗滑的扩大拱脚设计思路。采取理论研究、数值计算以及现场实测相结合的手段，对抗滑大拱脚对地层的变形影响进行研究。研究结果表明，抗滑大拱脚能够明显地控制隧道围岩拱顶沉降的同时，对隧道围岩的收敛起到更加有效的抑制作用，主要是因为扩大拱脚中的抗滑脚嵌入围岩中，能够产生侧向抗力，阻挡大拱脚向隧道临空一侧侧移。进一步的研究表明，从抗滑大拱脚的受力情况分析来看，抗滑大拱脚的抗滑脚的长度与围岩的级别有关，在控制相同围岩变形情况下，随着围岩在III级～VI级的变化，抗滑桩的长度则随着增长，嵌固深度增加，并呈现非线性变化。

Abstract：The arch foot with an expansion section can be applied to well control deformation of large-section tunnels built in soft layers. Based on previous researches，the structure of arch foot with an expansion section is further developed，it presents a method designing an anti-slide arch foot in the tunnel. The effects of the large arch foot on the deformation of the strata are studied by theoretical study，numerical calculation and field measurement. Research results show that the anti-slide arch foot in the tunnel is able to control convergence of surrounding rocks of the tunnel effectively，as well as control settlements of vault of the tunnel. It happens mainly because the anti-slide arch foot with an expansion section is inserted into the surrounding rock，which can produce lateral resistance and prevent the arch foot from moving towards the side of tunnel near the air. Furthermore，the research results reveal that the length of the arch foot is related to classification of surrounding rocks considering mechanical behavior of arch foot subjected to forces. Under the same surrounding rocks，the length of arch foot and its ends that inserted into the soil increase nonlinearly if classification of the surrounding rock varies from III to VI.

Key words： tunnelling engineering large section tunnel anti-slide arch foot with an expansion section field tests convergence numerical simulation
