摘要
膨胀土的抗剪强度是膨胀土地区路基、边坡设计的重要依据,其参数选取一直是膨胀土研究领域的重要课题。结合南阳地区膨胀土的抗剪强度研究,对其现场剪切试验的试样制备及试验方法进行探讨,提出了膨胀土抗剪强度的修改计算公式。通过反算证明,文中的现场剪切试验方法及抗剪强度的计算公式是合理的。
The determination of shear strength for expensive soil is always an important research object in this field. The shear strength is of much significance in the design of road foundation and slope in the expensive soil area. Taking the expensive soil in Nanyang Area, Henan Province, as study case, the in-situ shear test method, including preparing samples and test method, is proposed in the paper. The improved formula of calculating shear strength of expensive soil is suggested based on test data, and employed to determine the parameters. The results of landslides stabilities indicate that the method suggested is rationale.
