郭母子滩滩性复杂,属于两峡之间开阔河段滩险,浅、急、弯及险的碍航特性并存。采用疏浚与筑坝结合的整治方案,选取5组整治方案进行物理模型试验,根据整治前后的分流比、流速、流态等指标综合比较,最后推荐方案5为郭母子滩整治实施方案。

Guomuzi beach is classified to open river beach between the ravines,which preserves the following impeding navigation features: shallow,anxious bent and danger.The renovation scheme adopts both dredging and building dam.And then five kinds of regulation schemes are selected to carry out physical model test.According to the test results,the recommended scheme is the fifth renovation plan,after the comparison among the split ratio,velocity,and flow state,etc.
