WU Bin;Shangqiu Water Conservancy Construction Survey Design Institute;
In order to calculate the depth of the stilling basin conveniently,the paper proposed a simplified method for calculating the energydissipation. In this method,while maintaining the highest water level on the gate,we didn't use the gate opening height to calculate thedischarge,however,it used the maximum design discharge as an upper limit;we used hierarchical discharge in the dissipation calculation.The main calculation parameters included:water depth of the outlet of the basin,discharge per unitwidth,total potential energy,and waterdepth after hydraulic jump,waterdepth of shrink section,water drop of the outlet of the basin,etc. According to the calculation results ofhierarchy,we could determine the depth of the stilling basin.Simplified algorithm of dissipation canceled the complicated flow calculation ofsluice opening,reduced the amount of calculation,and applied conveniently. The results indicate that the simplified calculation method canmeet the requirements of the sluice energy dissipation in plain area,but the application should be controlled and experience should be learnedduring the actual operation of the sluice,to sum up procedures which can enable the project secure and conveniently management.
