As a result of interaction of tectonic subsidence, silt sedimentation and embankment, the geo environmental system of Middle Reaches Basin of Yangtze River has been separated into two parts with different evolution tendencies:(1)the outside of embankment is an artificial over fed basin; (2)the inside of embankment is an artificial starved basin.

In this article, a new kind of embankment technique of shell tubular pile of large-diameter placing-in-situ concrete is introduced.

The embankment along the main channel has quickly developed as a result of population moving from the North China to this area.

The general engineering situation,engineering condition,engineering design and construction,and engineering characteristics of retaining dike reclamation project of Jiangsu Datang Lusi Power Plant are presented.

The Pilot area for land reclamation and soil improvement for the container berths and multi-purpose berths in Phase III of Miaoling Port Complex of Lianyungang Port was dammed with a retaining dike which was built with three different structures,namely,riprapping to displace muck,riprapping by blasting to displace muck,and sand piles and sand quilts.

The measures for seepage control of a dyke were analyzed.

Preliminary Prediction of Earthquake Hazard of Earth Dams and Embankments in Pearl River Delta;

In recent years,the middle and lower reaches of the Xijiang River bed under the cut for variety of factors,the floods washed away the embankment caused by highly dangerous section to force the deep offshore,endangering the safety of the embankment.
