摘要:Based on static load test results, with consideration of the small-strain stiffness characteristic of soils, the bearing capacity of bored piles with pile-toe and pile-shaft post-grouting have been analyzed using HS-small model and HS model of Plaxis program. The analysis reveals that: the small-strain stiffness of soil is not negligible in analyzing pile and soil interaction; with post-grouting, the interface between pile and surrounding soil are strengthened and the performance of bored pile is improved with increased bearing capacity and reduced settlement.
