Abstract


The Huanghua Port as an important port of the west-east coal , has been completed in 2001 , has been well received by the serious siltation troubled of the outer channel . As 2007 entered Yiduntaigang \Since the 1980s , many research institutes , construction units , and universities has been engaged in the study of the Huanghua Port waters siltation regular , and has accumulated a large amount of measured data . The the Huanghua Port sea area of historical data and research results based on the basic hydraulic characteristics and motion characteristics of the nature of the Huanghua Port, Coast and sediment , and analysis of the basic reasons for the rapid deposition of the formation of the outer channel and the following conclusions : Huanghua Port Coast named silt Coast or silty mud Coast , and is gradually formed after the abandonment of the old Yellow River estuary retreat after a long period of erosion and destruction ; Huanghua Port outer channel of the rapid deposition is mainly caused by the large waves , \, the trend of sediment siltation characteristics of the sea ; the channel siltation of major sediment source for Huanghua Port on both sides of shoal sediment waves ( large waves ) caused by tidal currents starter , migration and deposition ; the Huanghua Port waters of the sediment most of the nearly underlying handling mainly the bottom of hyperconcentrated water to explain once gale outer channel of the formation of the hundreds of ' reasonable siltation from sediment concentration angle . On the basis of analysis of the reasons for the rapid deposition of the the Huanghua Port siltation calculation mode and remediation engineering principles , and the use of numerical example shows the effectiveness of remediation project Deposition Reduction , which provides the basis for the implementation of the remediation project . According to field observations after the Huanghua Port extension dike construction , remediation works have played a role to mitigate siltation , the analysis and calculation mode is more reasonable .
