中文摘要：
将裂隙岩体中的基质用等效连续介质模型描述，裂隙用离散网络模型描述，采用等效连续介质模型和连续，离散裂隙耦合模型模拟了裂隙岩体中的水流和溶质规律，并根据实测的裂隙倾向、倾角、隙宽等几何因素，应用随机的方法产生了裂隙网络。基于洪水期和枯水期的实测地下水位对耦合模型的参数进行了率定，模型的预测结果显示，采用耦合模型而不是等效连续介质模型预测的结果与实测数据拟合较好。在裂隙发育的区域，局部地下水位出现了异常，示踪剂的迁移速度较快，采用连续．离散裂隙耦合模型能够有效地模拟这一异常现象。
英文摘要：
A coupled model of fracture flows was employed in this study to simulate the flow and solute transport in fractured rocks, where porous matrix is represented using the equivalent continuum model and discrete fractures is described with a discrete-fractured network model. The data concerned in the fractured orientation and aperture were collected in the study area for generating the random fields of fractures. Model calibration was conducted using the data from the observed groundwater levels during the flood and dry periods. Results indicate that simulated groundwater levels and concentrations with the coupled model, instead of the continuum model, agree well with observed data. In the area of fractures developed extraordinarily, and of abnormal groundwater table where the observed groundwater table is lower than these of Yalong River stage, the coupled model can effectively capture and replicate the primary geological and hydro-geological characteristics in contrast to the continuum model.
