Numerical analysis of application for pile-supported reinforced embankment in subgrade widening engineering;

Several key problems of pile-supported reinforced embankment were studied by elastic-plastic finite element method,including the composition and distribution rule of the settlement,the applicable situation and the influence factors of pile efficacy.

Theoretical analysis of combined action of cushion and embankment fills in pile-supported embankment;

Both stiffened platform effect and soil arching effect are affected by the cushion,so the cushion becomes a key part in pile-supported embankment for pile-soil stress adjustment.

Study of soil arching in piled embankment with FEM;

Simplified method of settlement calculation and its application to piled embankments

The piled embankment is an effective method for controlling the post-construction settlement of embankment which has been emerged recently.

Numerical simulation and comparison of pile-net composite foundation with pile-supported embankment;

The pile-supported embankment is a new embankment structure introduced into China recently,which can control the residual settlement of the embankment reasonably and effectively and has a wide application prospect.

Taking Shen-Su-Zhe-Wan(SJZA) highway as engineering background,in-situ study of pile-supported embankment with pile partially penetrated in soft soils is carried out.

Three dimensional simulations on soil arching of piled embankments

Soil arching has significant influence on behaviors of piled embankments.

The analysis of soil arching is the first important issue for the design of piled embankments.
