长江上游宜宾—重庆河段航道整治新结构新材料应用*

山区河流具有滩多流急、水位暴起暴落、卵石推移质普遍存在的特点,对整治建筑物结构材料提出了更高要求。结合已实施的长江上游泸州—重庆河段、宜宾—泸州河段航道整治工程,对长江上游河流整治建筑物新结构新材料应用、施工工艺等进行总结,得出多项应用实例,在该河段航道治理中具有很好的适用性。这些治理经验的总结,可为其它山区河流航道建设提供借鉴。

Application of new structure and material in waterway regulation of the upper Yangtze River reach Yibin to Chongqing

Based on the characteristics of many shoal and rapids,rise and fall abruptly of the water level,ubiquity of graved bedload,it puts forword higher requirement on structure and material of regulating on mountainous river.According to the finished waterway regulation engineering of the upper Yangtze River reach of Luzhou to Chongqing and Yibin to Luzhou,this paper summarize the application of new structure and material,construction technology and so on that used and fit well in this river,obtains a number of application examples.The experience provides some reference for waterway regulation on another mountainous rivers.
