| Abstract: | Based on the practical engineering and aim at overcoming the defects of the traditional cement mixing pile method on treating deep soft embankment, this paper researches the application of PTC in the connection engineering of expressway and presents the design method of the rigid pile compound embankment. The results of the analysis show that treatment present obvious effects with prestressed sparse pile scheme. The method features with reliable quality and low coat and could provide reference to related engineering. |
