天津南港地区吹填土的流失率及控制试验研究

Experimental investigation of the loss rate and control technology of reclaimed soil in Tianjin Nangang district

文章以南港工业区港区航道挖泥结合吹填造陆工程为试验背景,采集吹填过程中的相关数据,对南港地区的吹填土流失率及相应控制进行研究。分析得到了土颗粒粒径、泄水口挡板上过水厚度、吹入量、库容、流径等因素与流失率的相互关系,为今后规范编制和类似工程的实施提供依据和指导。

Taking the project of channel dredging and reclamation in Tianjin Nangang district as the experimental background, this paper analyses the loss rate and the corresponding control of reclaimed soil in Tianjin Nangang on the base of the related data collected in the process of reclamation work. The correlations among the soil diameter, the water depth of drain opening, the amount of reclaimed soil, the capacity of reservoir, flow path and the loss rate are summarized to guide the writing of the relative standards and implementation of the projects in the future.
