摘要
通过潮流物理模型试验和泥沙回淤计算,分析研究二期港池向西至颗珠山深槽间浅滩挖通对一、二期工程港区的减淤作用。以及一、二期港池拓宽300m对一、二期工程港区的减淤影响。试验、计算结果表明:西部浅段开挖势在必行;港池加宽300m减淤作用不大;为求整体经济效益合理,应该辅以整治工程措施;预报与实测回淤量值比较,预报值仅偏大约10%,两者基本一致,说明预报是比较准确的。
Through the tidal current physical model test and siltation calculation,we analyzed the sedimentation reduction action on the harbor area of Phase I and Phase II due to the dredging off of the shoal between the Phase II harbor basin and Kezhu Mountain.We also studied the sedimentation reduction effect on the harbor area due to the widening （of 300 m width） of the harbor basin of Phase I and Phase II.The test results indicate that the excavation of the western shallow is imperative;The widening of harbor basin （of 300 m width） does little to the basin＇s sedimentation reduction;Regulation measures shall be taken to achieve the reasonable overall economic benefit;The predicted value is only 10% more than the measured one,which indicates that the predict value is accurate relatively.
