The field test and operation practice show that the blasting membrane as a measure for the regulation of hydropower station can be applied to those stations with high water head and long pressure diversion tunnel.
The design outlines and construction technology of circular prestressed anchorage cables by after tensioning used in lining of power tunnel of Geheyan hydropower station are described.
Since 1980s,for a variety of reasons in construction system,management ability,design and construction levels,the quality of partial works in Chinese water conservancy & hydropower project construction has been poor,resulting in serious quality accidents such as dam failure and intake tunnel concrete liner collapse etc.
Taking the Qiaoqi Hydropower Project as an example, the major engineering geological problems for long intake tunnel with thick overburden in hydropower project is systematically analyzed and prediction is made to provide references for the other tunneling projects .
How to construct safely and protect the environment upon the tunnel is the difficulty in dewatering technique in water tunnel construction. it' s the key to water tunnel construction.
(5) The above mentioned research achievements are applied to hydraulic fracturing analysis of liner of water tunnel in pumped-storage hydroplant at black dragon mountain.
Excavation of a 16-km water diversion tunnel from Northfield Mountain to Quabbin Reservoir in western Massachusetts may be undertaken from at least three shafts in addition to the outlet adit.
This study aims to determine the geotechnical characteristics of clays in the diversion tunnel of the 4 Eylül dam which will provide the water supply of Sivas city.
This paper discusses the engineering geological investigations, diversion tunnel support design and slope stability assessment studies carried out at the Sulakyurt dam site, northeast of Ankara, Turkey.
Direct measurements in a water tunnel showed that calculated values of critical velocity were slightly too high, but otherwise confirmed the role of the lunules.
