摘要
使用WDT-1500多功能材料试验机,对不同裂隙倾角下的非贯通裂隙水泥砂浆试件单轴循环荷载与静载组合条件下力学特性进行了初步试验研究,试验发现:随着裂隙倾角的增加,变形能先减小后增大,峰值强度先降低后增加,弹性模量呈上升趋势,破坏形态由剪切破坏向张剪混合破坏形式转变。
The non-piercing crack cement mortar mechanical characteristics of uniaxial cyclic loading and dead loading under different crack rake angle were elementary experimental researched with WDT-1500 multi-functional material testing machine. The experiment found out that the deformation energy decreased then increased along with crack rake angle increased, while the peak strength decreased then increased, the young＇s modulus was rising trend, the damage form changed from shear failure to extension and shear failure.
