厦漳大桥北汊主桥通航孔通航能力分析

Navigational Capacity Analysis of the North Navigable Span of Xiamen-Zhangzhou Bridge

厦漳大桥北汊主桥通航孔的通航能力与其上游及桥区附近的码头建设规模密切相关。以调研数据为基础,分析北汊主桥通航孔的特点及碍航性,提出通航净空高度是制约其通航能力的主要因素,通过实船数据的统计分析,论证北汊主桥通航孔的通航能力。其结论对该桥区通航安全管理及桥区上游和附近码头建设规模的确定具有参考价值。

The navigational capacity of the north navigable span of Xiamen Zhangzhou Bridge is closely related to the development scale of the wharves in its upper reaches and adjoining areas. Based on survey data, the features of the north navigable span and the obstruction of the bridge are analyzed. It suggests that the height clearance be the main factor conditioning its navigational capacity. Actual traffic statistics are analyzed to evaluate the navigational capacity of the north navigable span. The result of the study can be a guide for navigation safety administration and wharf de- velopment planning of the upper reach and adjacent areas of the bridge.
