Field test on technique of cap-pile supported embankment;

Through introducing soil arching effect theoretical research achievements,its practice in rigid retaining wall,embankment pile and anti-slide pile engineering had active effect to soil arching effect research and application.

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.
