A wide field in mattoon boasted easy access to a railway line , making delivery of the coal easy , and a sandstone substratum , apparently well suited for sequestering carbon dioxide 广阔的马顿市拥有通往铁路线的便利交通,使运输煤更加便捷,同时下层砂岩土显然非常适合碳封存。
The raft rigidity directly affected by the dimensions of the board , however , were neglected in the traditional analyzing of substratum settlement except of the elasticity theory method 除弹性理论法外,其它常用的设计和分析方法几乎都没有考虑筏板刚度对下卧层沉降的调节作用。
That would depend upon whether the germs of staunch comradeship underlay the temporary emotion , or whether it were a sensuous joy in her form only , with no substratum of everlastingness 那就要看在这番暂时感情之下牢固的友谊会不会生长发育了,或者说,是不是仅仅因为她的美貌而生出的一种感官上的爱慕,实际上却缺少了永久的性质。
At last the writer presents a new kind of control method in the paper . it tries to solve the problem of torque fluctuation only by change of control method , not by change of motor substratum 最后,本文还提出了一种新型的电机控制方式,这种新型控制方式旨在不改变电机本体的设计而只是通过控制方式的改变来解决通常的控制方式带来的转矩波动过大的问题。
Firstly , this paper analyzes the distribution of pile - top counter force , pile - end resistance and additional stress of the substratum influenced by raft rigidity in different loads and piles length . it proves the internal forces of foundations distribute unevenly 本文首先采用有限单元法分析了不同荷载形式,不同桩长条件下筏板刚度对桩顶反力、桩端阻力和下卧层附加应力等的影响。
The distribution of pile - top counter force and pile - end resistence influence the distribution of substratum ' s additional stress , and the latter farther influences the pile - top counter force inversely . contrasted to the result by geddes " formula , the same characters can be concluded 为简化计算,本文还将geddes公式应用于下卧层附加应力分析,其数值结果表明考虑筏板刚度的附加应力分布规律与有限元计算结果一致。
Finally , in section three , rayleigh wave exploration method is used in a practical project - northern stone material trade market . the embedded depth of cobble substratum of the whole site , and the regression equation between the test blow count ( n63 ) standard penetration and the surface wave velocity ( vr ) are obtained in the process . a good case study is provided for the practice of the subjected method in this section 第三部分是将瑞雷波法勘探应用于北方石材交易市场的工程实际中,得到整个场地的下卧卵石层的埋藏深度,并给出该场地的标贯值n _ ( 63 . 5 )与v _ r间的回归方程,为这一方法的应用提供了很好的工程实例。
On the base of compendious introduction of position , condition of traffic , choice substratum of this topic and studying significance of bamei eco - tourism region , the thesis has especially narrated strategic significance of developing tourism and regional geological background , has detailed introduced type and feature of tourism resource of bamei eco - tourism region , has deeply analyzed relation of tourism market supplying and needing ; after studying feasibility of conversion of resource and production , the author took the opinion of deeply development of tourism products , and detailed discussed on deeply development of tourism products of bamei eco - tourism region 文章在简略介绍了八美生态旅游区地理位置、交通条件、选题依据及研究意义的基础上,重点叙述了本区发展旅游业的战略意义及其区域地质背景;详细介绍了八美生态旅游区旅游资源类型及资源特色,深入分析旅游市场供需关系;在对资源-产品转化可行性研究之后,提出了旅游产品深度开发的理念,并按近期、中期和远期三个阶段对八美生态旅游区旅游产品深度开发进行详细深入地探讨。
Considering spatial axial - symmetry , finite element method ( fem ) is used to analyze the behavior of pile - soil unit ( also called " unit cell " ) , such as the distribution of the stress and deformation in reinforced regions and substratum . the law of load transfer between pile and soil is further revealed through the numerical analysis 进行了单桩复合体空间轴对称有限元数值分析,通过对填土荷载下单桩复合体加固区及下卧层的应力、变形进行数值模拟,进一步揭示桩、土的荷载传递规律。
