    • Abstract
  • Provided that the relationship between retaining wall deflection and earth pressure comply with hyper-bola model,the nonlinear earth pressure considering retaining wall deflection is built.The nonlinear earth pressure model based on the predecessors' researches on foundation pit active and passive zones,which builds like Dun-can-Chang model.Therefore,the parameter of the nonlinear pressure can be ascertained by conventional triaxial tests in the way Duncan-Chang model makes.The elastic resistance method connects with the nonlinear earth pressure,this makes elastic resistance coefficient definite.Taking "m" method as an example,the influence factors are analyzed.
