| 摘 要： | 对黄河口潮区界铺设河底管线的主要参数进行了计算分析,结果表明:管道穿越处在现有河势和最不利条件下,主河槽最大摆动宽度为1 000 m,河道最大冲刷坑深度位于滩唇以下13.5 m,两岸滩地最大冲刷坑深度为2.0 m;考虑管道穿越地层的适宜性,管底设计埋深应在滩唇以下23.0 m,相应管底高程为-19.4 m。

| Abstract: | The main parameters of the river bottom pipe installation in the estuary tidal zone of the Yellow River were analyzed in this paper.The results indicate that the fluctuation range of the main channel fluctuates about 1 000 m at the most unfavorable state,and the maximum deepness of the washout is about 13.5 m,at the same time the maximum deepness of the washout at the flood plains is about 2.0 m.In order to suit the pipe laying,the deepness of the depth of burial is about 23.0 m below the river beach,and th... |
