摘要
长江干线泸州至重庆河段为具有冲积性特征的山区河流。在川江上首次从优良河段的河相关系入手,运用等级流量比较法及稳定航深估算法,探求天然情况下长江干线泸州至重庆河段航道的开发潜能,分析得出了泸渝段优良河段的河相关系,证明了该河段具有整治开发到Ⅰ级航道的潜能,提出了该河段建设Ⅰ级航道的尺度标准。可作为规划、航道建设的参考。
The reaches from Luzhou to Chongqing are the mountainous rivers with the alluvial characteristics.Starting with the river channel morphological relationship of excellent reaches in Yangtze River for the first time,and using the comparative method for grade flow and estimation method for navigation depth,the channel development potential from Luzhou-Chongqing reach in the natural circumstances is studied,and the river channel morphological relationship of excellent reaches from Luzhou to Chongqing is obtained.The result shows that the reach has the potential to be improved and developed to the grade I channel,and the dimension standards of grade I channel construction are proposed,which can provide references for planning and channel construction.
