Reliability analysis of inverted filter under concrete slab of downstream protection slope for overflow earth-rock cofferdam;

Scour calculation and model experiments of overflow earth-rock cofferdam;

The damage degrees of two overflow earth-rock cofferdam with the same diversion standard and scheme were completely different after a flood with a discharge equaled 3 000m3/s.

Factors affecting the operating condition of earth rock overtopped cofferdam was systematically analyzed.

Application of finite difference method in seepage calculation of overflow rockfill cofferdam

Seepage problems of deepwater high earth-rock cofferdam in Three Gorges Project;

The blasting method for notch of the earth-rock cofferdam antiseepage wall at the second stage of chinese Three Gorges Project, the measurement results of water hammer wave are presented, the influential factors of affecting the intensity of water hammer wave are analyzed, the control opf explosive dose of notch and protection method are put forward.

Dabu power-plant had been successful in applying anti-leakage new technology of high pressure spraying guniting for earth-rock cofferdam on the blanket of gravels, which shortened construction period with good anti-leakage effect and obvious economic benefit.
