Abstract The installation angle of feet-lock pipe has a great influence on the support effect in controlling the subsidence of steel arch. In order to determine the reasonable installation angle，an analytical model of feet-lock pipe and steel arch is established based on a brief analysis of the working mechanism of feet-lock pipe. The theoretical correlation between the installation angle of feet-lock pipe and the vertical displacement of vault is derived using the theory of structural analysis，elastic foundation beam，etc. Then an example analysis is presented in detail to determine the reasonable installation of feet-lock pipe and explain the corresponding mechanism. Analysis indicates that the reasonable installation angle of feet-lock pipe is around 45°. More importantly，this proved to be a general conclusion which is consistent with lots of the experience from construction site. Accordingly，the formulas derived in this paper are proved to be correct. It can provide theoretical support for determining the reasonable installation angle of feet-lock pipe，and the conclusion could be employed in the related design and construction.

Key words： tunnel feet-lock pipe installation angle steel arch elastic foundation beam
