摘要
针对红黏土抗拉特性正确认识的不足,通过轴向压裂法和单轴拉伸法分别测定了武鸣红黏土的抗拉强度,并对比分析了两种试验方法及其测定结果,研究结果表明两种试验方法均能有效测定红黏土的抗拉强度,且具有很好的一致性,二者各有优缺点,在此基础上,探讨了武鸣红黏土抗拉强度与含水率之间的关系。试验结果可为正确认识红黏土的抗拉特性及裂缝处理方案设计提供合理的抗拉强度指标和相应依据。
Focusing on lacking of the correct understanding of tensile properties of red clay, the tensile strength of red clay from Wuming was measured by axial fracture test and uniaxial tension test respectively; and the similarities and differences between the two test methods and their results were compared. The result shows that both of them can determine the tensile strength effectively and the results have a good consistency, even though they have advantages and disadvantages. Furthermore, the relationship of tensile strength and water content of red clay was discussed. The results may provide the reference for a correct understanding of the tensile properties of the red clay and crack treatment program design.
