摘要
通过现场直剪试验与室内直剪试验方法成果进行比较,阐述了现场直剪试验方法的优点,对室内直剪试验存在的问题进行了探讨,分析说明现场直剪试验方法在矿山边坡勘查中的推广应用。饱和状态和天然状态下土的抗剪强度试验结果表明,孔隙水压力对边坡稳定产生较大影响。
Based on the comparison of the results and methods of in-situ direct shear test and direct shear test in a laboratory, the advantages of in-situ direct shear test are expounded and the problems existed in the direct shear test in the laboratory are discussed. It is proved that the in-situ direct shear test method can be widely used in exploration of mine slopes. The testing results of soil shear strength in saturation condition and natural condition show that pore water pressure has a big influence on stability of slopes.
