摘　　要：本文从研究边坡中地下水运动规律入手,分析坡体中的浸润线位置过高对边坡稳定的影响。提出了采用水平排水技术疏干坡体,防治滑坡的技术措施。通过现场试验,证明水平排水可迅速排除地下水,大幅度地降低浸润线,并有效地防止在雨季由于降雨入渗而使浸润线又重新上升。起到防治滑坡的作用。水平排水技术施工方便,费用少,可在粘性土质边坡中推广使用。The paper deals with the law of ground water movement in the slope and analyzes the effect of high phreatic line in the bulk on the slope stability.On this basis the measures of horizontal drain wells for dewatering the body of slope and preventing landslides are proposed.Field tests show that with this technique ground water can be drained away rapidly,the phreatic line can be lowered effec- tively,and the recovery of ground water table due to rain infiltration in the rainy season can be pre- vented.This Technique is convenient in construction and low in cost,and can be popularized to bring slide of clay soil under control.
