摘　　要：为探明降雨入渗时裂隙岩体非饱和区渗透荷载分布规律 ,利用自行设计制作的单裂隙渗流实验装置 ,对一垂直单裂隙在有降雨入渗条件下的非饱和区渗透荷载分布规律开展了一系列的实验研究。获得了有实用参考价值的非饱和区渗透荷载分布规律特征 ,弥补了以往采用各种假定进行非饱和区渗透荷载取值所存在的严重不足。这一实验成果为实际岩体工程的渗流稳定分析提供了实验依据和新的有效方法 。Distribution of seepage load in unsaturated areas of fractured rock during rainfall was analyzed through a set of experiments specially designed to study unsaturated flow in a single fracture with precipitation. The experiment modelled the distribution of seepage load in unsaturated areas in a single vertical fracture need specifics. The experimental data provides valuable analysis of the seepage load in unsaturated zone. A new effective method is proposed for seepage stability analysis to improve the safety and economies of seepage systems.
