Analysis indicates that there is little difference in the displacement of tunnel and well control of stratum displacement by both methods. Plastic zone develops more obviously above the tunnel side by CRD method and is larger by CRD method than by dual sidewall guide pit method. It is comparatively obvious that the plasticity district develops in the side direction of the tunnel by dual sidewall guide pit method and the leading influence distance is also longer than that by CRD method. The development speed of plasticity district is comparatively fast in the range of the leading 3~6 m in CRD tunnel and 0~3 m in sidewall guide pit tunnel. There are different advantages by both methods for passing through sand layer.
