摘要(Abstract)：

针对目前结构性黄土抗拉强度方面的研究成果较少,必须采用合理的试验方法对其进行测定与分析的问题,.通过对比目前应用于粘性土抗拉强度测试装置的优缺点,研制了一种可适用于饱和—非饱和结构性黄土抗拉强度测试的试验装置,并进行了调试运行,在此基础上对不同初始含水量的原状及重塑土进行抗拉强度的测试.研究结果表明:无论是结构性原状土还是重塑土,其抗拉强度随着含水量的增大而呈减小趋势;在相同含水量的情况下,在饱和状态二者的差异却并不大,同时,在相同含水量的情况下,原状土的抗拉强度要大于重塑土的抗拉强度.此外,对于结构性土而言,当含水量较低时,抗拉强度的值要达到300 k Pa,这是一个不可以忽略的量值..
