【摘要】 通过对陕南膨胀土在不同含水量下的直剪试验研究 ,结果表明膨胀土的含水量对其强度指标有着强烈的影响。并在此基础上建立了膨胀土剪切强度指标与含水量的关系计算公式 ,这为膨胀土地区的地质灾害防治以及工程设计及稳定性分析提供了依据。更多还原

【Abstract】 In this paper, according to the different water content, straight shear test study of expansive soil of the south of shaanxi was carried. The test results show that the intensity index is strongly affected by water content of the expansive soil. Base on the results, the author establishes the account formula about the relation of shear intensity index and water content. According to the results, it can be better for preventing and harnessing geologic hazard and provide the gist for engineering design and stability analysis.更多还原
