| Abstract: | Numerical simulation method is used to study the dynamic settlement process of dry mixing pile composite foundation during the construction of road foundation.Excess pore water pressure and consolidation settlement of soft soil foundation are analyzed with(permeation) flow analysis module and strain analysis module.Stress ratio of pile to soil of composite foundation is obtained to indicate the consolidation settlement and its process pattern. |
