摘　　要：通过分析漳卫新河的基本状况及未来航运发展对通航等级的要求,确定漳卫新河航道通航标准,考虑现有工程对拟建桥梁建设的制约因素,提出向下游搬迁船厂和改建沿海高速收费站2个解决方案,经过分析确定采用搬迁船厂的方案,并确定拟建桥梁最小通航净空尺度,进而判断拟建漳卫新河大桥的通航孔布置方案满足远期航运发展需要。By analyzing the basic situation of Zhangwei New River and the requirements of navigation grade for future shipping development, the navigation standard of Zhangwei New River channel is determined. Considering the constraints of the existing bridge construction pro - jects, this article puts forward two solutions： the relo - cation of the shipyard downstream and reconstruction of coastal highway toll station. After analysis, the scheme of relocation of shipyard is adopted, and then the mini - mum navigation clearance dimension of the bridge plan - ning to built is confirmed, so the navigation opening layout of Zhangwei New River bridge to meet the needs of long- term shipping development can be determined.
