After Huang Qu senior official yellow Jinlong looking pensive stopping, also in a low voice saying:"Knows, on the Earth 60,000,000 year ago dinosaur exterminate, it is said is because at that time a diameter reached 200 kilometers planetoids to hit Saturn high speed, caused the Saturn entire stratum and the earth's crust receives the undulation, and caused the fierce reverse volcanic eruption, finally acted according to the near several centuries the continually exploration research to indicate, Saturn periphery several satellites, and even the giant beautiful saturn's ring, possibly all was creates by this direct hit, moreover most surprising was, spouted the Saturn parent substance together after the burning hot Saturn lava material coagulation, formed the diameter reached 30 kilometer hit fragment, after is hit unexpectedly Saturn fierceSways the movement, flung the Saturn orbit rapidly ......"

黄区长官黄金龙若有所思的停了停之后，又低声的说道：&知道吗，地球上6000万年前的恐龙灭绝，据说就是由于当时一颗直径达200千米的小行星高速撞击土星，导致土星整个地层和地壳受到波动，并引起剧烈的反向火山喷发，结果根据近几个世纪的持续探索研究表明，土星外围的几个卫星，乃至巨大美丽的土星光环，可能都是由这次直接撞击造成的，而且最令人惊讶的是，一块喷出土星母体由炙热的土星熔岩物质凝固后，形成的直径达30公里的撞击碎块，竟被撞击后土星剧烈的摇晃运行，急速甩出了土星轨道……&

Groundwater system of Cretaceous system of Ordos basin in terms of system of water-bearing stratum of groundwater was divided and analysesed.

从地下水含水层系统的角度对鄂尔多斯盆地白垩系地下水系统进行了划分和分析。

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。
