Based on long-term monitoring convergence deformation of Wuqiaoling deep-buried long tunnel, this paper analyzes convergence deformation regularity of two parallel main tunnels. Results show the left main tunnel's convergence obviously exceeds that of the right, because the right main tunnel's construction absorbs the experience of the left main tunnel. Furthermore, authors research on rheology rule of Wuqiaoling tunnel by FLAC(superscript 3D). Numerical analysis result basically is consistent with actual measurement result. Finally, 6 principles to dispose soft wall rock rheology are presented.

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.

结果表明，采用这2种工法时引起的隧道变形相差不是很大，都能较好地控制地层的变形；采用CRD法时产生的塑性区较双侧壁法大，且向隧道侧上方发展较为明显；采用双侧壁法时产生的塑性区在隧道侧向发展较为明显，超前影响的距离也大于CRD法；采用CRD法时的塑性区在超前3~6m的范围内发展速度较快；采用双侧壁法时的塑性区在超前0~3 m的范围内发展速度较快；对于隧道穿越砂层而言，2种工法各有优势。
