水力插板透水丁坝缓流促淤效果试验研究
Experimental Study on Effect of Sedimentation Promotion with Tranquil Flow of Hydraulic Flashboard Permeable Spur Dike
摘要
Abstract
In view of flood control effect was not obvious in Xinjiang riverbed made of sand,by developing river engineering movable bed model test and theoretical analysis,for effect of sedimentation promotion with tranquil flow of hydraulic flashboard permeable spur dike and hydraulic flashboard entity spur dike,well-pole pile permeable spur dike in contrast test research were conducted. The outcomes show that the velocity after dam of three types of spur dike is lower,the velocity behind the hydraulic flashboard permeable spur dike decreases by about 46%,the velocity at hydraulic flashboard entity spur dike and well-pole pile permeable spur dike decreases by about 16% and 30%respectively;there is no obvious recirculation region after dam,the height of deposition after dam of hydraulic flashboard permeable spur dike is greater than the other two spur dikes;hydraulic flashboard permeable spur dike is better than hydraulic flashboard entity spur dike and well-pole pile permeable spur dike on maintaining its own stability.关键词
