摘要
为了有效治理长江南通河段，制定经济、合理的整治工程方案，在南通河段潮汐河工模型上，进行了各整治工程方案的定床和局部动床试验。通过综合分析，提出了稳定南通河段现有河势工程措施和改善现有河势的整治方案。
In order to realign Nantong river section, draw up economic and reasonable regulation works,the tidal river model of Nantong river reach was designed and set up.Fix-bed and partial moving-bed experiments about various regulation projects of this river section were conducted.By comprehensive analyses,engineering measures forstabilizing present Nantong river reach and regulation programs for improving itsexisting river shape were put forward.
