灌河口开发和外航道整治研究 总被引:4,自引:0,他引:4
通过对灌河口上海和外海来水沙量及外航道历史演变的分析,表明新沂河汇共泽藻河口的河床有较大影响,上游各支流的下泄量较小,外海的来水来沙量主要与纳潮量和外海波浪对海底掀沙能力的大小有关。外航道整治方案回淤量计算结果为:开挖万吨级航道泥沙回淤量为220万m^3/a,开挖3.5万吨级航道回淤量为320万n^3/a,航道开通后,燕尾港可分期建设8个万吨级泊位。 相似文献

In this paper the effect of accelerating silt accumulation of the composite project of groin system with different spacings and detached dyke constructed on the silt coast is analysed, taking Dingshan accelerating beach accretion project in Ruian County of Zhejiang Province as an example. The above-mentioned is discussed from the aspects of deposit pattern of the beach surface, rule of deposition and deposition rate within the groin basins. On the basis of these analysed results, the principle of overall layout for constructing this kind of project and the proposals for selecting the rational structures are presented. 相似文献
