摘　　要：以小型挡水闸为研究对象,结合工程实例,针对小型水闸上游铺盖不同部位出现裂缝时,闸基的渗透坡降、总水头以及渗流量等因素进行了统计分析。当上游铺盖裂缝距离闸室越近时,闸基渗流入口及渗流出口处的渗透坡降值越大,相应的总水头递减速率越大,水头变化波动性也相对较大,对应工况的闸基渗漏量越大。结果表明,水闸上游铺盖的裂缝位置距离闸室越近,对闸基的渗流稳定性越不利。This paper takes the small sluice as the research object. An analysis of the cracks was made combining with the engineering examples,which will appeared at different parts of the small sluice＇s blanket. And the results were analyzed with statistics,which include the seepage gradient,total head and seepage flow. The results show that the seepage gradient at the entrance and outlet will be larger when the blanket crack is close to chamber. And the total head＇ s decreasing rate together with the seepage flow will be changed in the same situation.
