Based on the improved three-dimensional finite element model, this paper studies load transfer mechanism of pile-supported reinforced embankments. The model uses an elastic medium to replace soft soil subgrade, which reduces calculation depth subgrade and improves efficiency model. validity is proven by field test results theoretical results. By changing cohesion, internal friction angle, modul...

Piled foundations are commonly employed to reduce settlements of artificial earth embankments on soft soil strata and geosynthetic reinforcements installed at the embankment base increase pile spacing construction costs. Despite well-documented effectiveness this technique, mechanical processes, developing during in different elements constituting ‘geo-structure’, not fully understood design ap...

The collected field data from well-instrumented reinforced embankments in the framework of a real project for extension inner-city area at HafenCity Hamburg is used to study effect environmental changes on load transfer process over structure lifetime. A particular focus put improve understanding mechanism soil embankment pile foundations through geosynthetic layer and investigate corresponding...

In this work, the settlement deformation of soft-soil subgrade and law geogrid were studied based on field tests carried out pile-supported reinforced embankment Rongwu Expressway in Xiong’an New Area. The reinforcement area underlying layer embankment, transverse longitudinal sections subgrade, bidirectional analyzed. results show that reducing pile spacing height can effectively reduce founda...

A quasi-three-dimensional finite element method of analysis is proposed for the dynamic response analysis of pile foundations that is computationally feasible for practical applications. The method uses a simplified three-dimensional wave equation for describing the dynamic response of the soil. The response of the pile foundation is computed directly without having to use pile–soil–pile intera...

A new efficient and accurate hybrid reliability method is proposed to estimate risk of an axially loaded single pile considering pile-soil interaction effect. Uncertainties associated with all the design variables are considered appropriately. It intelligently integrates the concepts of the response surface method, the finite difference method, the first-order reliability method, and an iterati...
