| The settlement property of composite ground under flexible embankment load is a complicated program in geo-technique recently. Directed against this, through in-situ test, FEM, theoretical calculation, the author makes out some adequate conclusions.The author studies the settlement and stress properties of composite ground under flexible embankment load though in-situ tests. This paper studies the settlement rule with the load and time changing and achieves the suitable pile-soil ratio which is suitable for the composite ground under flexible embankment load.Based on the program of MARC, the paper uses the plane problem finite element to study the properties of composite ground under embankment load. The author analyses the settlement factor of influence.The author analyses the composition properties of after-construction settlement based on studying two construction case through data processing and theoretical calculation. The paper studies the reinforcement mechanics of DJM pile and presents the calculation equation for after-construction settlement.The author simply discusses the applicability of the fitted curve method for after-construction settlement prediction and achieves some useful conclusions. |
