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。
