韩国Janghang海堤工程防洪闸泄流能力试验研究

Experimental study on floodgate of Janghang seawall project in South Korea

综合比较了韩国工程设计部门提供的和中国水利工程的平底闸堰流、孔流过流量计算式后指出,计算中应考虑河道闸前行近流速水头的影响.进行了韩国Soli河防洪闸设计方案和比较方案的水工模型试验,从防洪的角度来看,比较方案优于设计方案.

Differences between formulas applied in engineering design departments of South Korea and in Chinese hydraulic engineering for calculating flow capacity of the flat-bottomed sluices and orifice flow are compared. Results show that influences of the approach velocity head before a sluice should be considered in calculation. Hydraulic model tests for the design scheme and comparison scheme of the floodgate of the Soli River in South Korea are carried out, and the results show that the comparison scheme is better than the design one in terms of flood control.
