查询词典 sand

The expedition had taken with them an elderly Arab whose main qualifications as a guide were that he had crossed the sand sea twice before in his lifetime, once as a young lad. To the expedition's amazement , he had kept the vehicles at an exact compass bearing right across the sand sea, apparently based solely on his recollection of minor features in the landscape (a hump on the horizon or a patch of unusual red sand) that he had seen only twice many years before.

该远征队随行带上了一位年长阿拉伯人，他作为向导的主要资格就是他平生曾两次穿过这个大沙海，其中一次他还是个年青小伙子，令远征队叹服的是，他带领车队迳直横穿沙海时与罗盘方向完全吻合，显然他全靠回忆那些只在多年前见识过两次的细小的地貌特征(如地平线上的一个土丘或者一片非同一般的红色沙漠)。

Second, considering the influence of well resistance, smear effect and structure breakage of thick soft clay, the equivalent calculation method is proposed. That is, the partially penetrating sand drain ground is viewed as the double-layered ground, and its consolidation is analyzed with 1-D consolidation theory, through the transformation from 3-D consolidation to 1-D consolidation in the region of sand drain. This can overcome the disadvantage that the excess pore water is discontinuous between the region of sand drain and under-lying soft layer. To the double-layered ground, based on the consolidation mechanism under surcharge, the excess pore water pressure calculation formula is deduced under the condition of multilevel equably loading or unloading, which perfects the consolidation theory.

然后，在充分考虑竖井区井阻、涂抹作用以及土体结构损伤破坏对固结影响的基础上，将未打穿竖井地基合理地转化为双层地基，按一维固结理论计算，克服了传统固结计算方法在竖井处理区与下卧层交界面处存在孔压间断的缺点；在此基础上，从超载预压法的基本原理出发，分析了双层地基超载预压固结、沉降机理，推导了多级等速加、卸载情况下双层地基的固结计算公式，进一步完善了双层地基固结理论。
