| 中文摘要: |
| 针对长江上游王爷庙—兰家沱河段航道计划尺度边界问题，采用对多年航道预报尺度及实测水位数据进行统计分析的方法，同时参考实际航道维护经验，得出该河段重点水道为温中坝、东溪口和叉鱼碛水道，各重点水道的航道计划尺度边界分别为泸州羊角滩水位0.95 m、斗笠子水位0.30 m、小桃竹水位0.60 m，降低维护尺度的方案为舍深保宽。 |
| 英文摘要: |
| Aiming at the problem of conditions for waterway falling below planned scale in the Wangyemiao to Lanjiatuo river section of the upper reaches of the Yangtze River，we use the method of statistical analysis of the multi-year waterway forecast scale and the measured water level data，and refer to the actual waterway maintenance experience.It is concluded that the key waterways of this section are Wenzhongba，Dongxikou，and Chayuqi waterways.Conditions for waterway falling below planned scale of each key waterway are that the water level of Yangjiaotan in Luzhou is 0.95 m，the water level of Doulizi is 0.3 m，and the water level of Xiaotaozhu is 0.6 m.The plan to reduce the maintenance scale is reducing depth to preserve width. |
