金沙江下游库区翻坝码头结构型式及适应性分析

Study on the Structure Type of Port Wharf in Jinsha River Downstream Reservoir and Adaptation Analysis

金沙江腹地矿产资源丰富,资源输出需求大,但金沙江通航设施与翻坝运输能力的不足,已经成为制约库区航道货运能力的主要瓶颈,国内对翻坝运输系统中的超大水位差,长变动回水段码头水工结构型式研究少。本文总结了常用的内河库区码头结构形式,并根据库区水文条件、地形地质环境,结合翻坝货物需求特点,分析并提出了适用于金沙江翻坝码头水工结构型式,为金沙江下游各翻坝码头建设提供参考。

Jinshajiang hinterland is rich in mineral resources and has a large demand for resource output. However, the shortage of Jinshajiang navigation facilities and dam-turning transport capacity has become the main bottleneck restricting the shipping capacity of the waterway in the reservoir area. There are few researches on the hydraulic structure type of the wharf in the dam-turning transport ayatem at home and abroad. This article summarizes the common-structural forms of wharf in the inland river reservoir area, and analyzes the preliminary hydraulic structure types applicable to the Jinshajiang dam-turning pier based on the characteristics of the dam turning pier above and below the dam, combined with the on-site waterway, hydrology, terrain and geological conditions. The scheme, combined with the characteristics of the existing structure of dam-turning docks in China, proposes several reasonable and applicable general layout forms of dam-turning docks, which provides a reference for the construction of dam-turning wharfs in the lower reaches of the Jinshajiang.
