【Abstract】 The composite pile-geonets is effective to consolidate soft foundation for some constructions which have special requirement for non-uniform settlement and residual deformation, because its interaction mechanism and loading transmission is a complex problem. In this paper the stress dispersion principle is applied to estimating the loading on geotextile and pile, then the tensile strength and secant modulus are calculated. The result provides a theoretical basis for designing pile-geonets.更多还原
