摘要
总结了淤泥质海岸航道建设期的泥沙回淤监测内容和常用的定性分析、定量计算方法以及成果校核验证方法等。以天津大沽沙5万吨级航道为例,给出了其建设期的泥沙回淤监测分析成果,主要包括泥沙回淤厚度和淤积量的计算及成果校核、回淤时空分布规律、开挖前后回淤泥沙的物质组成变化情况、淤泥层厚度及密度垂向分布状况现场监测等。
This paper sums up construction of the channel. Taking the the contents and methods of survey and analysis of the sediment during Dagusha channel for an example, the achievements of survey analysis of siltation during channel construction including the calculation and verification of the depth and volume of sediment deposited in the channel, the regularities of spatial and temporal distributions, the change of physical constitute of sediment before against after dredging, the field survey of depth and vertical distribution of density of mud in the channel, etc., are presented.
