Analysis on the Comparison and Selection of Soft Soil Foundation Treatment Methods
In order to explore the advantages and disadvantages of different soft soil foundation treatment methods,and better apply them to engineering practice,this paper takes the Bay Area Avenue engineering in Dongguan Binhaiwan Bay Area as the background,and uses the finite element software Midas GTS to establish the sand drain surcharge preloading soft foundation treatment model and the deep mixing pile composite foundation treatment model.The settlement deformation,stress change and economic benefits of soft soil foundation under the two treatment methods are analyzed.The results show that both treatment methods can effectively reduce the settlement of soft soil foundation,the settlement deformation control effect of deep mixing pile treatment method is better,and the construction period is shorter,but its cost is higher.The research results can provide reference for the selection and application of sand drain surcharge preloading method and deep mixing pile composite foundation method in practical engineering in the Pearl River Delta region.
