| 摘 要： | 本文采用直剪方式对砂浆试块进行了抗剪断试验研究,得到了它的抗剪强度参数和若干剪应力-位移全程曲线,并就法向应力对残余强度的影响以及残余强度与峰值强度的关系作了初步探讨。结果表明,砂浆试块剪断以后,内聚力c基本消失,内摩擦角φ几乎不变,残余强度及其与峰值强度的比值随着法向应力的增加而增加。

| Abstract: | A test study about the shearing resistance is conducted on several mortar blocks,from which we get the shearing strength parameters and some complete curves of shearing stress displacement.Also,this paper analyzed the influence of normal stress on residual strength and the relationship between the residual strength and peak strength.The outcome indicates that the parameter 'c' will lose its function,while another parameter 'φ' will continue its work after the mortar blocks are clipped,and that both the residual strength and its ratio to the peak strength have an increasing trend with the normal stress. |

| Keywords: | mortar clipping normal stress peak strength residual strength |
