摘　　要：水库大坝在不良环境影响下容易出现滑坡等病害,且现有碾压土石坝设计规范未将降雨、蒸发作用所引起的稳定性问题考虑在内。对此,论文通过建立数值模型的方式,探讨了土石坝渗流及稳定性与库水位、降雨、蒸发作用的联系,并根据现场实测资料详细分析了滑坡等病害成因。Dams in reservoirs are prone to landslides and other diseases under the influence of bad environment,and the existing design codes for rolled earth-rock dams do not take the stability problems caused by rainfall and evaporation into account.In this paper,the relationship between seepage and stability of earth-rock dam and reservoir water level,rainfall,evaporation action is discussed by establishing numerical model,and the causes of landslides and other diseases are analyzed in detail according to the field measured data.
