Examples
- Abstract : the course - keeping ability of a naval patrol ship in following waves is analyzed by means of a practical approach consisting of semi - captive model test , semi - empiric numeric modeling , and numerical simulation . the assessment result in the form of stability border can then be applied for comparative study of different design concepts and as well for development of operation guideline
文摘:本文用半约束模型试验技术、半经验数值模型和数值模拟实用方法分析了一艘巡逻艇在随浪中的航向保持能力.并给出了以稳性界限形式表示的评估结果,它可适用于不同设计概念的比较研究以及工作指南的开发 - 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。 - Geotechnic centrifuge model test technique utilizes the equivalence between centrifugal force field and gravitational field ; model dimension dwindles into 1 / n times of prototype " s , but the body force on the model increases n times . the strain and stress of model is equal to prototype " s , but the displacement of prototype is n times of model " s
土工离心模型试验技术利用离心力场和重力场等效性，将模型尺寸缩小到原型尺寸的1 / n ，同时作用在模型上的体积力增大n倍，这时，模型中各点的应力、应变与原型中对应点的应力、应变相等，原型和模型对应点的位移成n倍关系。
