Abstract: After the Three Gorges Reservoir was built，the experience value could not be applied to determining construction levels of inland mountainous river． After taking Cuntan Wharf as an example，the monthly average water level and water level after the completion of each month in natural situation were analyzed and the number of days of continuous construction was obtained． The said number was compared to the estimated construction period based on engineering quantity; adjustments were made according to specific flood of special circumstances． Compared to traditional method of experience， the present one was more accurate and reasonable and it could play a positive role in improving construction quality and reducing costs．

Key words: wharf in mountainous rivers, Cuntan, construction water level

摘要： 三峡成库后，经验取值的方法不再适用于内河山区河流码头建设的施工水位确定。以寸滩码头为例，分析了 码头所在河段天然情况下历年各月平均水位、成库后各月水位后，得出可连续施工天数;结合工程量，将其与预计 施工工期对比，再视特殊具体洪水情况，作出调整。该方法较传统经验取值法更为准确、合理，对施工质量及经济 效益等方面都有积极作用。
