干燥细砂破坏形式试验分析

Test and Analysis on the Failure Type of Dry Fine Sand

土体破坏不是偶然的现象,受控于多种因素,而这些因素均为变量,不能精确地知道它们的数值。土体的结构是指土颗粒或集合体的大小和形状、表面特征、排列形式及它们之间的连接特征,也是影响土体破坏的多种因素之一。文章通过模型试验发现细砂的破坏是多种形式的综合体,其中土体的密实度、颗粒大小、级配等均是影响土体破坏形式的重要因素。

Damage of soil body is not a phenomenon by chance.It is due to multiple factors,which are all variables with their values could not be precisely obtained.The structure of soil body refers to the size and shape of soil grain or aggregate,appearance feature,disposition display and the character of their interconnection.It is one of the factors related to the soil damage.Through model test,the Paper finds out that the failure of fine sand body is due to the combination of multiple factors,among which,the density,grain size,gradation etc.of soil body are the important factors contributing to the failure of soil body.
