结合实际工程，对敷设在水库集水区内集渗廊道的一部分进行1∶1的模型试验测试，得到了该工程条件下，廊道内渗滤体在不同工作水头时单位面积的渗流量和廊道的总集水流量，并计算出不同工作水头下渗滤体的渗透系数。在此基础上，对滤体垂直放置及水平放置的渗流能力进行了对比。结果表明：集水廊道的集水流量与廊道内滤体的特性和尺寸有关，在建造廊道前应先行选择；廊道的集水流量在不同工作水头下是不一样的，设计时应与水库运行和防洪要求相协调；在渗滤体的渗透系数一定时，廊道内渗滤体的面积越大廊道的集水流量越大，工作水头越高廊道的集水流量也越大；在水流条件相同时，同一渗滤体水平放置和垂直放置的集水流量是有差别的，渗透系数不相同，设计不同体形的廊道时应加以注意。

Combined with specific engineering,a 1∶1 model tests of a portion of the seepage-collection gallery in the reservoir is conducted to test the seepage quantity of per unit area and the total quantity of catchment in different working heads. And the seepage coefficients of the filter medium corresponding to the different working heads were calculated in this paper. In addition to these experiments and calculations,a trial in which the filter medium was located vertically and horizontally was made to compare its seepage capability. The results show that:the seepage quantity of the seepage-collection gallery is related to the characteristic and size of the filter medium,so we must select the right fil-ter medium before conducting the gallery;seepage quantity is different in different working heads,therefore the seepage quantity should be co-ordinated with the reservoir operation and the requirement of flood control in designing;when the seepage coefficient of the filter medium is a certain,the larger area of filter medium,the more seepage quantity,and the higher working head,the more seepage quantity;the seepage quantity and seepage coefficient of the same filter medium in the same water flow condition,are different when located vertically or horizontal-ly,for this reason we should pay attention to different forms of galleries in designing.
