天津港30万吨级航道建成后港区泥沙回淤分析

摘要

Tianjin Port is the largest man-made port in China.In recent years,under the implementation of the strategy of deep-water,the grade of the waterway has been raised to 300,000 dwt.Based on the measured data and laboratory test results,the hydrological and sediment environment of Tianjin Port and the hydraulic characteristics of sediment were analyzed.At the same time,with the measured water depth map and mathematical model,the siltation intensity and distribution of the port of Tianjin Port under the conditions of 300,000 dwt waterway were analyzed comprehensively in order to provide the basis for annual maintenance and dredging plan of Tianjin Port.%天津港是我国最大的人工港,近年来在港口深水化战略的实施下,航道等级已经提升到30万t级,通过实测资料和室内试验结果,对天津港海域的水文泥沙环境以及泥沙的水力特性进行了分析,同时利用实测水深图和数学模型计算,综合分析天津港30万t级航道建成后港区淤积强度以及分布规律,以期为天津港年度维护疏浚计划的制定提供依据.
