摘要
本文通过选材、试配、试验等过程找到了一种模拟表土地层的相似材料;并对试验结果进行了分析,同时,研究了组成相似材料的几种材料的性质、作用以及对相似材料的物理、力学性质的影响;由于配了四个重块,提高了直剪试验结果的准确性。
In this paper,by selecting material,testmixing and testing process,etc.,one king of similar material for imitating topsoil strata was found,and test result was analysed;at the same time,the nature,function of several kinds of materials that the similar material consists of and its effect on physical and mechanial character of similar material was studied;the writer of this paper also makes four weights so the accuracy of direct shear test result was improved.
