通过河床演变分析 ,指出了射阳港口电厂河段码头前沿淤积的原因 ,提出了整治原则与整治工程方案 .经过定床、动床河工模型试验 ,优化了整治工程方案 .工程实施两年后的河段地形与试验结果几乎一致 ,且整治效果十分明显 Through the analysis of the river bed evolution, the reasons of siltation in the forefront of the pier of Sheyang Port Power Plant are pointed out, and the remediation principles and remediation project are put forward. After the fixed bed and movable bed river model tests, the remediation project is optimized. The terrain of the section is nearly identical with the test result, and the remediation effect is very obvious
