采用互相关分析方法研究了降雨过程中渗透系数K-s、土壤粘聚力c'和土壤内摩擦角tan φ'的非均匀性对边坡稳定性时空不确定性的影响。我们发现tan φ '和c'的相对重要性取决于有效应力。虽然稳定性对K-s变异性的敏感性较小,但Ks变异系数较大可能加剧孔隙水压力的变异性。因此,表征该领域的水力特性和孔隙水分布的非均质性是稳定性分析的关键。(C)2017爱思唯尔有限公司版权所有
A cross-correlation analysis is conducted to determine the impacts of the heterogeneity of hydraulic conductivity K-s, soil cohesion c' and soil friction angle (tan phi') on the uncertainty of slope stability in time and space during rainfall. We find the relative importance of tan phi' and c' depends on the effective stress. While the sensitivity of the stability to the variability of K-s, is small, the large coefficient of variation of Ks may exacerbate the variability of pore-water pressure. Therefore, characterizing the heterogeneity of hydraulic properties and pore-water distribution in the field is critical to the stability analysis. (C) 2017 Elsevier Ltd. All rights reserved.
