中文摘要：

岩体交叉裂隙的水流分配特性对揭示水体运移规律、人工疏导地下水、优化水力压裂方案等具有指导作用。文章利用自制裂隙渗流实验装置测试了常见＂一进两出＂＂人＂字裂隙开度、交叉角度变化时的流量分配特性。利用交叉控制体模型和雷诺输运方程分析了产生流量差异的原因。结果表明,偏流来自惯性力与裂隙壁面法向力作用产生的漩涡;流量分配只受进口和旁路裂隙开度的影响,与交角和水力梯度无关;旁路流量比（旁路流量与进口流量之比）与裂隙开度间存在实验幂次定量关系。

英文摘要：

Flow distribution characteristics of cross cracks in rock mass play aguiding role in revealing the water movement pattern,groundwater artificial channeling and optimization of hydraulic fracturing scheme,etc.In this paper,using a home-made crack seepage experimental device,the flow distribution characteristics of common herringbone cracks（so called＂one way in two ways out＂）with different crack openings and different cross angles were experimentally measured.Taking advantage of cross control volume model and Reynolds transport equation,the reason of flow difference was analyzed.Results show that bias current is caused due to the vortex produced by the interaction between inertia force and normal force of crack surface.Flow distribution is only affected by inlet and bypass crack opening,and has nothing to do with the angle and hydraulic gradientd.The bypass flow ratio（the ratio of the bypass flow and inlet flow）has the experimental power of quantitative relation with crack opening.
