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1.5~2.5 m，整治线宽度取为350~470 m，工程实践效果良好，河段
达到芋级航道标准。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 river stretch a fine waterway.
