Abstract

Abstract

No-sand concrete micro-pile post-treatment technology has the obvious effect on processing weak subgrade and expressway broadening.Through field research it was introduced effects of the treatment.Finite element numerical models were established to analyze the stress of powder-jetted piles and no-sand concrete micro-piles,excess pore pressure change and deformation characteristics of the typical embankment section,so as to verify effectiveness of its use.Through the parameters analysis,the using condition of the soil coefficient of permeability was obtained.By analyzing powder-jetted piles and no-sand concrete micro-piles in the condition of different pile length,regularities of exceed pore pressure,road embankment settlement and the stress ratio of pile-soil were obtained.Which provided a theoretic guide for further use of no-sand concrete micro-pile post-treatment technology.
