摘要：
Both of the stress field and deformation are unsymmetrical for shallow tunnel under unsymmetrical pressure and geological disaster such as collapse is easily to take place. This brings about troubling problems to both design and construction. In this paper, a case of Hongshigou tunnel is studied. Aiming at dealing with the problem of low buried and unsymmetrical pressure situation of tunnel entrance, a series of numerical studies has been done based on Flac(3D), after analyzing the characterization of stress field, displacement field and plastic zones, conclusions are gained as follows:1) 2) These conclusions can provide beneficial reference to design and construction for tunnel engineering.
