京广线K650上、下行两条曲线位于黄河铁路大桥南头100米处,属高路基地段。曲线另一头接黄河南岸车站道岔,高差大,纵坡达4.5‰;曲线半径小,R为804m;车流大,通过总重由1994年0.8亿吨km/km到目前1.4亿吨km/km增大1.8倍,列车通过速度高,下坡速度快,上坡要加速闯坡,客车速高达120km/h,货车速达80km/h,就货车离心力一项来说,由60km/h,提到80km/h,离心力增加率就达77.8%;按车辆编组由以前的40多辆增加到现在的60辆左右,采取信号四显示列车间隔进一步减少,使车轮对钢轨的连
Beijing-Guangzhou line K650, down two curves located 100 meters south of the Yellow River Railway Bridge Department, is a high sub-base section. The other end of the curve is connected to the turnout at the South Bank Station of the Yellow River with a large elevation difference of 4.5 ‰. The radius of the curve is small with a R of 804 m. The traffic flow is large with a total weight of 80 million tons km / km in 1994 to 140 million tons km / km Increased by 1.8 times, the train through the high speed, downhill speed, uphill to speed up the slope, the bus speed up to 120km / h, the truck speed of 80km / h, truck centrifugal force a from 60km / h, mentioned 80km / h, the rate of increase in centrifugal force reached 77.8%; by vehicle grouping from the previous more than 40 vehicles increased to about 60 now, to take the signal four further reduce the train interval, so that the wheels on the rail even
