为探讨红粘土路堤边坡降水影响深度，采用非饱和湿热耦合有限元分析方法，模拟了长期气候作用下及考虑裂隙作用下边坡瞬态水分迁移过程。计算分析得出，气候作用下路堤边坡湿度场分布主要受降水和蒸发影响，连续大雨暴雨时降水影响深度达2.0～3.0 m，连续中雨小雨时降水影响深度为1.0 m 左右，偶然大暴雨时降水影响深度为1.5 m 左右，持续无雨时影响深度可达3.0 m 左右；考虑裂隙作用的降雨影响深度为裂隙埋深加上气候影响深度，降水对红粘土路堤边坡湿度的影响范围可达4.0 m 左右。

To study the precipitation influence depth of laterite soil embankment slope,unsaturat-ed soil moisture-heat coupling finite element analysis method is used to simulate the moisture migration under the action of long-term climate and fissure.The calculated results indicate that Humidity distribu-tion is mainly affected by precipitation and evaporation,when continuous torrential rain the precipitation influence depth is up to 2.0 ~3.0 m,while continuous light rain is about 1.0 m,occasional heavy rain is about 1.5 m,and continuous sun is about 3.0 m.Considering the crack effect,the influence depth is equal to the crack depth and climate influence depth,and the rainfall influence depth of the laterite soil embankment slope is up to about 4.0 m.
