摘　　要：某水电站调压井边坡利用FlAC3D有限差分软件建立三维数值模型,在模型上合理、系统布置位移监测点,采用fish语言编程提取监测点位移,分析边坡在施工期的动、静态位移分布规律和发展趋势,以确定边坡潜在失稳区域和评判治理效果。结果表明,运用监测点位移分析方法综合评价研究区边坡的稳定性,可以较准确地预测边坡的发展变化趋势和危害性,并提出合理支护措施建议,为工程边坡治理提供了较为可靠的理论依据。The three-dimensional numerical model is built by using FlAC^3D finite difference software for surge shaft slope of some a hydropower station.In the model,the displacement monitoring points are lay out reasonably and systematically,and the programming,compiled by fish language,is used to extract the displacement of monitoring points,the dynamic and static displacement distribution laws and development trends of the slope are analyzed during the construction period to determining the potential instability area of the slope and judging the treatment effect.The results show that the comprehensive evaluation of the slope stability in the study area by using the monitoring point displacement analysis method can predict more accurately the development trend and the hazard of the slope and some reasonable support measures are proposed,which could provide some reliable theoretical basis for the engineering slope management.
