Calculation and analysis of the flood of the Baige Plug Body
In order to calculate the damage of the outburst flood to the downstream towns,the turbulent and negative wavefront flow intersection method and the experimental formula of the Yellow River Hydraulic Research Institute were used to calculate and analyze the collapse flood and flood evolution.The results show that the maximum flow rate of the"11·3"White Grid Plug is 175175.94 m3/s,which is 4.17 times larger than the measured value of 33900 m3/s.The storage time of the whole plug is 4.88 hours.Compared with the measured flow rate at the downstream section,the error varies from 10.7％to 127.7％.The farther the downstream section is from the location of the fracture,the smaller the calculation error.The closer to the section at the breach,the flood flow process line is pointed,away from the section at the breach,the smoother the flood flow process line,and the variation of the section depth water process line is consistent with the trend of the section flow process line.
