摘　　要：文中通过小型土石坝坝高和筑坝材料统计分析,了解筑坝材料不同物理特性的统计特征。针对某工程实例,进一步分析渗流和坝坡的稳定性,得到筑坝材料不同物理特性对坝坡稳定的影响规律。结果表明,筑坝材料相关物理特性统计数据相对离散,尤其是抗剪强度参数和渗透系数。抗剪强度参数对下游坝坡的稳定性起决定性作用,充分重视其离散性。渗透系数和湿容重对坝坡稳定也有一定影响,亦不容忽视。This study investigates the statistical characteristics of dam height and construction materials for small earth-rock dams.tI explores the statistical features of different physical properties of construction materials.Based on a specific engineering case,further analysis of seepage and dam slope stability was conducted to understand the influence of different physical properties of construction maetrials on dam slope stability.The results indicate that the statistical data related to the physical properties of construction materials are relatively discrete,especially the parameters of shear strength and permeability coefficient.The shear strength parameters play a decisive role ni the stability of downstream dam slopes,and their discreteness should be given sufficient attention.The permeability coefficient and wet bulk density also have a certain impact on dam slope stability and should not be ignored.
