Study On Design Theory And Numerical Simulation Of The Ground Improved With Dynamic Consolidation Method

Theoretical and applyment researches have been done gradually since its creation by L.menard in 1968.The dynamic considation method has been widely applied in ground treatment,but there are no universally applicable theory for studieson it and accurate designation for it.Based on the condition of the Gan Zhou Jiang Yuan science and technology development limited company,conducts the systematic study of the ground improved with dynamic consolidation method by dedign construction parameter,effect examination and numerical simulation.This thesis includes the analysis discussion of consolidation mechanism,study on design theory and construction parameter,study on the project application and effect examination,numerical simulation of the ground improved with dynamic consolidation method.By deeply analyzing soil's consolidation theory and shock wave theory,it discusses dynamic consolidation mechanism of the ground.By combining some present code of our country nowadays and some projects practice,it specifically expands design method of dynamic consolidation and the method of selecting the dynamic compaction parameter.And put forward the method which was used in Gan Zhou Jiang Yuan science and technology development limited company has achieved desired effects.At last,this thesis analyzing the numerical simulation of the ground improved with dynamic consolidation method.Numerical simulation obstains the condition of consolidation center point's vertical direction displacement of dynamic consolidation process,displacement,stress and strain in the course of dynamic consolidation by the Flac.The result of numerical simulation again achieved desired effects.This thesis conducts more systematic study on design theory and numerical simulation of the ground improved with dynamic consolidation method,already obtained the conclusion to dynamic consolidation method the further study and the project application has the certain help.
