Abstract

Abstract

The settlement of pile-group consists of the compression deformation of pile shaft and the settlement of pile tip. In this paper, the compressive deformation of single pile shaft is calculated by adopting hypothesis of linear-elasticity, and the compressive deformation of pile-group shaft is approximate to the compressive deformation of single pile shaft. Moreover, the additional stress of pile tip is obtained by multiplying the average stress under pile cap or raft and the coefficient of transfer load. All these researches deduce the means of calculation of pile-group settlement with soft underlying straturr, In the end, the present method is compared with another method and practical project test results.
- pile-group settlement,
- compressive deformation of pile shaft,
- coefficient of load transfer,
