摘　　要：通过对毛细透排水带进行试验,测试其抗淤堵性能。在清水和浑水条件下,对滤料渗透系数、毛细透排水带与滤料组成的综合渗透系数进行对比分析,结果表明,在清水情况下,毛细透排水带与滤料组成的综合渗透系数是未采用毛细透排水带原滤料渗透系数的407.0～544.3%;在采用浑水进行27次试验后,试验段从上至下4段的综合渗透系数分别是清水综合渗透系数的46.0%、58.5%、64.5%和83.9%。试验表明毛细透排水带能显著提高综合的渗透系数,并具有较好的抗淤堵性能。The experiments are conducted for testing the anti-clogging capability of capillary drain belt in pure water and muddy water respectively.The result of the experiments indicate,that the synthesis permeability coefficient of capillary drain belt with filter is 407.0～544.3%of that of filter only.In muddy water experiment, after adding 27 times muddy water,the synthesis permeability coefficient of capillary drain belt with filter are 46.0%,58.5%,64.5%and 83.9%of that of pure water in 4 section layers from top to bottom. Capillary drain belt Capillary can increase the permeability coefficient of filter,and have better anti -clogging capability.
