Research On Construction Technology Of Thick Soft Foundation Under Water Filled Embankment

Levee is a water retaining structure built along the edge of the river,canal,lake,coast or flood diversion area,flood diversion area and reclamation area.Embankment is one of the most widely used flood control projects in the world.The embankment is flood defenses and protect residents and the main measures of agricultural production.The constraints will limit line after the flood,flood spillway,etc.to increase the flow of flood water depth,flow rate increases,is conducive to the flood discharge.The dikes can withstand the wind and the waves.In this paper,the design and construction of dike are studied based on the construction of the comprehensive regulation project of the Red Lake in Jiujiang.Mainly do the following work:(1)Engineering layout and main building design.Firstly,dike line layout,based on the analysis of the hydrological and engineering geological data,considering the embankment line direction,the impact of regional protection and the scope of project investment benefit,the selected dike line layout.Through the comparison of the scheme,the section of the dike is determined,and the main technical parameters are determined.(2)compaction analysis.The main difficulties and Red Lake embankment construction engineering is the key through the lake has deep silt layer of the lake,so the safety and construction scheme of integrated engineering considerations,in order to have a stable foundation and accurate quantity,save the project investment,must carry out in-depth analysis on the process of compaction.(3)research on construction technical scheme.Because of the high thixotropy and rheology of the soft soil foundation such as silt,how to construct the silt has been the difficulty of water conservancy construction.In this paper,the application of the results of the analysis and calculation of the silt is used to guide the construction,and through the comparison of the field experiments,the most suitable construction scheme is selected.The results show that the analysis and calculation results are reliable and can be used to guide the construction.The correct selection of the construction scheme is of great significance to the safety and quality of the project construction and to save investment.
