棱柱状结构

棱柱状结构体试件破损过程的试验研究

Experimental study on breaking process of prismatic structural bodies

试验发现，在棱柱状结构体试件的破损过程中，结构体表现出劈裂、剪切和压碎的破损方式，最后形成破损带；

During the breaking process of structural bodies , it is found experimentally that the main failure modes of structural bodies are splitting , shear failure and crushing , but finally the breakage bands form ;

通过棱柱状结构体在不同排列方式下的平面应变压缩试验，研究了侧向应力卸载状态下结构体的破损过程，探讨了结构性岩土材料在卸侧向应力状态下的变形和破损机理。

In order to explain the failure and breakage mechanisms of structural geological materials , the plane strain compression tests of the samples of prism-like structural bodies assembled in three patterns are conducted under unloading conditions .

试验发现，在侧向应力卸载的过程中，棱柱状结构体会发生错动和结构体的破碎，结构体的破损方式主要有劈裂破坏和剪切开裂两种。

In the process of reducing the lateral stress , it is found experimentally that the structural bodies will be broken after some relative movement and the main failure modes of structural bodies are splitting and shear failure ;
