To discuss the feasibility of applying this technique into the practice of engineering, this paper references the real project of the running tunnel from Great Showplace to Scientific House in Shenzhen Metro, uses the geotechnical centrifuge of Southwest Jiaotong University, then researches the settlement of the ground and the influence on the pipeline underground in stratum with abundant water by the technique of undraining spin-spay pile, at last draws a conclusion about the principle of the ground settlement with the construction method of excavating soil rich in water without dewatering at Shenzhen Metro.

为了探讨离心模型试验技术这一研究手段在地下工程中应用的可行性，结合地质、水文、结构较为复杂的深圳地铁大～科区间暗挖施工SK3+355断面的具体实例，应用我校新近建成的100gt土工离心试验机，采用离心模型试验技术对在富水地层应用水平旋喷桩工艺进行控制降水施工对地表沉降变形及地下管线的影响进行了研究。

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。
