Fluid-mechaincal Interaction Analysis Of Levee Engineering

Dike is the world’s most widely adopted as an important flood control projects, theembankment is a major flood defense measures to protect people ’s lives and property.As an important dike embankment pattern has been widely adopted, embankmentconstruction process not only easy but also locally. Embankment in China has a historyof thousands of years, is still widely used even in economically developed countries,the embankment is the perfect combination of hydraulic engineering and landscapeworks, not only has the effect of flood control also has visual effects. For theembankment during construction and operation of the project, not only to consider thesettlement deformation stable levee levee, but also take into account the effect of porewater pressure flow generated for the entire project.In this paper, Nandu flood control Engineering to seepage finite element method tocalculate the theoretical model and geotechnical constitutive relation based on thetheory, to achieve fluid-structure interaction analysis calculated by FLAC software.According to the engineering calculation and analysis of the actual survey data leveeseepage stability data on the settlement. Guiding significance and reference value forthe construction of similar construction projects. The main contents of this paper are asfollows:(1) Combined with engineering field survey data, using FLAC software,engineering analysis and calculation filling layered filling construction to reachsettlement deformation generated during the design elevation, excess pore waterpressure generated during the period of construction, and the dike settlement bodystabilizing influence and settlement curves calculated levee.(2) Analysis to calculate the water side of the levee welcome to meet the designflood level and the formation of a stable flow conditions, not flood levee embankmentproject on the role, and levee seepage seepage control measures under the conditionsset. Coupled analysis results meet the water side of the toe of the dike embankment inthe center of the back side of the toe of the water displacement and pore water pressurechanges in the data. The results show that the water side welcome to meet the designflood level and the formation of a stable flow of the case, the overflow soil slope isgreater than the value of the need to increase the allowable seepage measures meet the water side.(3) Analysis to calculate the water side of the dike welcome to meet the designflood level and the formation of a stable flow conditions, changes in the levee seepageadditional measures in case of seepage。...
