为了对顺德水道乐从主要险段进行综合整治，在分析险段险情成因的基础上，提出适合该险段特点的综合工程治理方案，并结合河工模型试验进行了研究。试验表明，各方案实施后险段的河势都有不同程度的改善，流速分布趋于均匀，主流线中（右）移，险工段河床冲刷强度减弱。整治工程实施后，工程效果良好。
為瞭對順德水道樂從主要險段進行綜閤整治，在分析險段險情成因的基礎上，提齣適閤該險段特點的綜閤工程治理方案，併結閤河工模型試驗進行瞭研究。試驗錶明，各方案實施後險段的河勢都有不同程度的改善，流速分佈趨于均勻，主流線中（右）移，險工段河床遲刷彊度減弱。整治工程實施後，工程效果良好。

In order to carry out the comprehensive renovation of the main dangerous section of Shunde waterway in Lecong, based on the cause analysis of danger, a comprehensive renovation program has been put forward which is suitable for the characteristics of the danger, and combining with physical model test to validate research.And it is shown that the effect is good.The regime of the dangerous section has different degrees of improvement after the implementation of the program, in addition, the mainstream line moves to the middle or right, and the riverbed erosion is weakening.
