The influence of particle breakage on deformation and strength properties of calcareous sands was investigated using artificial calcareous sands and triaxial testing.
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。
Based on the different compression behaviors of natural and reconstituted calcareous sand, it is presented that the additional void ratio can cause particle breakage of natural calcareous sand.
根据重塑和原状钙质砂压缩特性的不同,提出颗粒破碎会引起原状钙质砂的附加孔隙比增量。
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.
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。
It was shown that the quantity of particle breakage increased with the increase of compressive stress and was related to the particle size.
结果表明:颗粒破碎量随着压力的增加而增加,并与粒径大小有关。
Through the triaxial tests of the coarse-grained material, the particle breakage under the isotropic consolidation, peak strength and different stress level conditions are studied.
通过三轴颗粒破碎试验,研究了某粗粒料等压固结、峰值以及不同应力水平下的颗粒破碎规律,分析了干湿状态的影响。
