摘　　要：在长江中下游历史险情资料调研的基础上,提出了一种盲沟管与传统人字沟相结合的新型导渗结构,并开展了不同水力梯度下不同土工织物长期淤堵试验和新型导渗结构排水物理模型试验。结果表明:改进后的盲沟管具有良好的反滤排水特性和抗淤堵特性,可为汛期散浸险情抢险提供参考。Based on the investigation of historical dangerous situations in the middle and lower reaches of Yangtze River,we propose a new type of permeable structure combining blind drainpipe with traditional herringbone groove.To evaluate the drainage performance of the new seepage structure,we conducted long-term clogging tests on different geotextiles under varying hydraulic gradient and drainage physical model tests of the new permeable structure.Results indicate that the improved blind drainpipe boasts excellent antifiltering and drainage properties.The findings provide valuable insights into effective measures for responding to diffuse and infiltrated hazardous conditions during flood season.
