在单裂隙饱和-非饱和渗流实验成果的基础上,建立了有降雨入渗下的三维裂隙网络饱和-非饱和渗流数学模型,并相应开展了三维正交裂隙网络饱和-非饱和渗流实验研究,分别从渗流时自由水面及降雨下非饱和区渗透荷载分布规律两方面进行了实验验证分析。通过理论计算与实验结果比较,证明单裂隙饱和-非饱和渗流实验关系式是合理可行的,由此所建立的三维裂隙网络饱和-非饱和渗流数学模型具有较好的实验基础。
Based on the testing results of saturated-unsaturated seepage in single fracture, a mathemalical model of saturated-unsaturated seepage of 3-D fractured network under rainfall is proposed. Corresponding testing study in a 3-D orthographic fracture network is carried out. The analysis of testing verification on water table and seepage load in unsaturated region under rainfall is made. The testing results of saturated-unsaturated seepage in single fracture are revealed reasonable through the comparison with theoretical computation, so that the mathematical model of saturated-unsaturated seepage of a 3-D fractured network under rainfall deduced from the results of single fracture has a sound basis.
