| 摘 要： | 由于膨胀土的裂隙性和超固结特性,膨胀土的抗剪强度不仅是膨胀土地区边坡设计的重要依据,而且一直是膨胀土边坡研究领域的重要课题。本文以南阳膨胀土为例,对膨胀土现场抗剪试验的试样制备及试验方法进行探讨,通过对该地区典型滑坡反算证明,文中的现场抗剪试验方法及抗剪强度的计算公式是合理的。

| Abstract: | The determination of shear strength of expansive soil is always an important research topic due to its fissuring and over-consolidation property. The shear strength is of much significance in the design of slope in the expansive soil area. Using the expansive soil in Nanyang Area, Henan Province as an example this paper discusses in-situ shear strength test method including specimen preparation. The improved formulas for estimation of shear strength of the expansive soil are also presented. The results of landslides stability analysis indicate that the method suggested is rationale. |
