Abstract
This paper introduces a three-dimensional numerical model of simulating the tunneling cycle of tunnel-type anchorage by the large finite element software ABAQUS. With tunneling cycles, the space-time effect for footage is analyzed comparatively, which are between the tunnel in headings and tunnel in foots. There are three parameters for evaluating the construction methods, that contain vertical displacement of tunnel vault, vertical displacement of tunnel invert, and horizontal displacement of tunnel wall. The results show that all the values of the above parameters are in the control. Hence, the construction methods of the engineering are available.
