基于有机质对红黏土物理力学性质的影响,在水泥加固条件下通过三轴试验,探讨有机质含量、水泥掺量、含水率和抗剪强度指标之间的关系,并对试验结果进行回归分析。研究结果表明,随着有机质和水量的增加,水泥土的抗剪强度不断减小;而水泥掺量的增加,则使得抗剪强度逐渐增大。但是,当各影响因素超过一定值时,变化幅度都在减缓;并且在相同试验条件下,外加剂的使用可以提高c、φ值。
Based on the influence of organic matter on the physical and mechanical properties of red clay, the relationship between organic matter content, cement content, moisture content and shear strength index was discussed through the triaxial test under cement reinforcement conditions. The regression analysis was carried out on the test results. The results show that with the increase of organic matter and water, the shear strength of cemented soil decreases; while the increase of cement content, the shear strength increases. However, when the influence factors exceed a certain value, the change range is slowed down; and under the same experimental conditions, the use of admixtures can increase c, φ values.
