摘　　要：饱水软基上筑坝，渗透固结过程是关键因素之一。本文以务坪水库软土地基筑坝为例，根据勘探、试验、设计成果，进行筑坝全过程数值模拟，根据计算结果进行回归分析，讨论渗透固结系数、水平排水距离及时间因素的敏感性，最后提出控制筑坝速度及存在问题，为安全筑坝提供一定的定量依据。One of the critical factors concerning dam construction on the water-saturation soft soil foundation is the seepage consolidation process. Taking the dam construction on soft soil foundation at Wuping Reservoir for example, based on the result of exploration, test and design, an overall process numerical simulation was carried out during the dam construction. In accordance with calculation result, a regression analysis was made, the seepage consolidation coefficient, horizontal drainage distance and the sensitivity of time factor were discussed. Finally,the speed control of dam construction and some problems left were proposed for some quantitative bases to build dams safely.
