摘　　要：为了合理确定宜宾至重庆河段浅滩的整治水位和整治线宽，采用多种方法相结合，并结合各滩险的具体情况综合确定，整治水位取为设计最低通航水位以上1．5～2．5m，整治线宽度取为350～470m，工程实践效果良好，河段达到Ⅲ级航道标准。同时，分析认为低水整治下通过建整治建筑物来调整河床形态以趋向于优良河段，效果是很有限的。In order to define the water level and width of regulation of the shoals in the stretch of the Changjiang River from Yibin to Chongqing, different ways and methods were used with a view to the specific circumstances of the shoals so that the water level after regulation takes 1.5-2.5 m above the minimum navigational level and the width of regulated river stretch for navigation takes 350-470 m. With the regulation works being completed, the waterway in the regulated river stretch complies with the standard for a navigational waterway of Class III. But the analysis showed that the effect of regulation is very limited if the regulating structures are built to adjust the bed formation to make the fiver stretch a fine waterway.
