Research on anti-seepage for rockfill dam on deep overburden;

Study on seepage flow property of deep overburden at a hydropower station;

Study on deep overburden upon side slopes of site for lower dam of Luohanping Reservoir;

Study on joint type for cut-off wall of deep overburden layer

Based on the massive experiments,such as the pellet analysis,the penetration coefficient,the dry density,the relative density,the load,the distortion,side presses and so on,the river bed deep overburden layer physics mechanical properties,the hydrology geology characteristic,its physical mechanics parameter is proposed.

This paper gives a brief introduction to the present development situation of the construction of faced rockfill dams on deep overburden layer both at home and abroad.

Combined with the sluice project which will build on the deep and thick overburden,the stable seepage of the foundation under the scheme of taking the full enclosed-type concrete cut-off wall was calculated with the 3-D finite element method.

It is constructed on the basis of deep and thick overburden, the sluice foundation is in the poor uniformity including the structure, the physics and mechanical property.

Cognition of geological problems of thick overburden layer;

Stability influence analysis on trench wall of seep proof screen in thick overburden layer

The paper introduced the experimental study on curtain grouting for dam foundation of Huangjinping hydropower station in thick overburden layer.

Numerical analysis of seepage filed in deep overburden foundation;

For constructing dam on the deep overburden foundation,it is very important for dam body and foundation to control seepage stability and seepage discharge.

Based on actual engineering of 350m high core dam building on deep overburden foundation,the stability of dynamic strength of sensitive materials,which existed in super-high core rockfill dam located in meizoseismal region and overburden foundation is discussed.
