NUMERICAL MODELING METHOD FOR SLOPE STABILITY UNDER VARIABLE DISTRIBUTION OF STRENGTH PARAMETERS

  • 摘要: 滑坡岩土体强度参数具有空间变异性,采用统一强度参数进行数值建模计算不能很好地体现这一客观性质对结果的影响.本文提出一种考虑岩土体力学参数空间分布下的滑坡数值建模方法,通过对滑坡地形地貌和有限的勘察数据进行控制边界下的插值补充,形成参数分布云图,结合Visual Basic和FISH编程将差异分布的参数加载到数值网格模型中,使理论模型和实际更接近.算例分析结果表明该方法可行,能更准确显示出滑体变形破坏部位及特征,对后期变形监测和治理有指导意义.
