摘要
为研究岷江老木孔防洪堤对库区河段河床演变、行洪能力及上下游和左右岸的影响,采用河工定床清水试验对4种堤线布置方案进行了比选,并通过对方案的水位、比降、流速、流态等系统观测,分析了各频率洪水位对乐山大佛、乐山城、库区河道的行洪能力、通航条件和建港条件等影响,初步拟定了优选方案。
In order to study the influence of the flood dike on the riverbed evolvement, flood capacity, upstream and downstream, and the left and right banks of Laomukong reservoir area in Minjiang river, the river fixed bed test of clear water is conducted for the selection of four dike line layout schemes. Through the systematic observation of the water lev- el, slope, flow velocity, flow pattern of four dike line layout schemes test, it analyzes the influence of its frequency flood on the Leshan Giant Buddha, Leshan City, river flood capacity in the reservoir area, the navigation conditions and construction of port conditions. Finally, the preferred layout scheme is determined.
