| 摘 要： | 利用人工钙质砂和三轴剪切试验手段，就颗粒破碎及其对钙质砂变形和强度特性的影响进行分析研究。结果表明，颗粒破碎程度与对其输入的塑性功密切相关；颗粒破碎的发生使钙质砂剪胀性减小，体积收缩应变增大，峰值强度降低。

| Abstract: | The influence of particle breakage on deformation and strength properties of calcareous sands was investigated using artificial calcareous sands and triaxial testing. The results indicate that particle breakage depends on the sample′s plastic work received during testing, and reduces the volume expansion and peak strength of the sands. |

| Keywords: | calcareous sands particle breakage deformation properties strength properties. |
