Abstract

Geosynthetic-reinforced and pile-supported embankment，has been considered as an effective and economic solution to reduce the total and differential settlements of the embankment constructed on soft soil. In this paper，a simplified method for analysis of an embankment on soft soil and supported by a rectangular grid of piles and geosynthetic is proposed. In this method，the soil arching effect is analyzed by arching effect in granular material initially proposed by Low B.K. et al.，and subsoil resistance，geosynthetic effect and especially load transmission of pile and soil are taken into consideration. Quadratic parabolic equation is employed to described the deformation of the geosynthetic. Ultimately the expression for subsoil resistance has been deduced，and then the tension and the deformation expression of geosynthetic can be worked out. Through comparative analysis with field test and other current design methods，it is found that the proposed method is conceptually and mathematically simple，and the results agree well with field test data and that of several current design methods.

Key words： pile foundation pile-supported embankment load transfer mechanism soil arching effect subsoil resistance tension of geosynthetic
