The Analysis Of Geotechnical Test Data And The Numerical Simulation Of The Dike Seepage In Gorges River Reservoir

Seepage issues and seepage deformation have been two important reasons fordangerous situation of dikes. The seepage analysis of levee and both research statusand developing process of the seeping damage have been investigated. It hasimportant reference value and ptactical significane for analysing and evaluating thesafety of the dike as well as taking reasonable seeping measures. Test parametersincluding compaction，particles’analysis,specific gravity and liquid-plastic limit insoil test are predicted and analyzed using intelligent algorithms.Using maximum drydensity, specific gravity, particles’analysis and limiting moisture content as modelinput, infiltrating coefficient as predicting output and analyzing value of infiltratingtest and model output value comparativly can verify the feasibility of a smartalgorithm for data prediction and can be used as references for infiltrating tests aswell as approximation for infiltrating coefficient that projects required.This articlelinks with protection project of XiaJiang reservoir area and uses finite elementsoftware to analyze the seeping conditions of the dike to provide basis for protectingworks in this project.The main contetnts are as follows:One,Introduce test methods for compaction， particles’analysis,specificgravity,liquid-plastic limit and infiltrating coefficient and use test parameters got formsoil test as input and output value in intelligent algorithm and predictive analysis model.Two,For less geotechnical engineering test data,select SVM algorithm that canspecifically address the problem of small sample in intelligent algorithms.Analyzedata in geotechnical tests and compare with FOAGRNN and BP algorithm to verifythat the SVM algorithm is of high-precision for small sample training.Three,Combined with design data of the dike in XiaJiang Project,use finiteelement software to model and analyze the dike and get the conditions of theseepage.Based on the results of infiltrating analysis,use measures for controling theseepage and introduce the construction process of preventing seepage methods forthe dike and the main methods of construction.
