To valuing the interlock strength of gravel base, we also had done large-scale straight shearingtest in door.
同时，为了评价粒料的嵌挤强度，还进行了室内大型直接剪切试验。

A single axle penetration and direct shear tests, through uniaxial penetration and direct shear correlation of direct shearingtest proved reasonable and effective.
进行单轴贯入和直接剪切试验，通过单轴贯入和直接剪切的相关性证明直接剪切试验合理有效。

The CBR test, slake durability test, compressing test and shearingtest of the dry and wet redstone granular soil samples were respectively carried out in this paper.
