| Abstract: | Base on model test,principle of bearing capacity of post grouting pile in silt are discussed.The influence of grouting range and volume are analyzed by examining the distribution of grouting body.A simplified design method and the numerical simulation models are proposed based upon analysis of effect of grouting.The calculation results manifests that influence of grouting range can't neglected for estimation of bearing capacity of post grouting pile. |
