长江上游重庆主城胡家滩河段为典型的大比降山区卵砾石河段,具有比降大、水流急、航宽航深不足等特点,文中依据其实际平面形态与该航道的通航标准,分析了其通航能力的现状与不足,在此基础上,参照山区卵砾石河流的整治原则,文中研究探讨了科学有效的整治方案,并借助地表水模拟软件对整治方案的整治效果进行了验证。从整治效果来看,文中方案很好地改善了胡家滩河段的航道条件,有效的增大了航深与航宽。文中研究成果可为同类河段的整治提供依据。
The upper reaches of the Yangtze River in Chongqing Huchengtan main section of the river is a typical large area of lower pebbles in the mountain, with a larger than the current, the water emergency, lack of breadth of deep navigation and so on. According to the actual plane shape and the channel navigation standards , Analyzed the status quo and deficiencies of its navigable capacity, on this basis, with reference to the principle of remediation of mountain pebbles and rivers, the paper discussed and discussed the scientific and effective remediation programs, and verified the remediation effect of remediation programs by using surface water simulation software . From the remediation effect point of view, the program in the paper has improved the waterway conditions of Hujiatan well and effectively increased the flight depth and the breadth of navigation. The research results in this paper can provide the basis for the remediation of similar river sections.
