“Fill a lake, start an earthquake”: Damming and Reservoir-Induced Seismicity
(April 4, 2000) A paper by Heather Gingerich, a medical geologist who specializes in hydrogeochemistry and the director of the Canadian chapter of the International Medical Geology Association, detailing evidence in support of reservoir-induced seismicity RIS as a distinct geophysical phenomenon causally related to reservoir impoundment. Continue reading →
Ship lift at Three Gorges Dam, China — design of steel structures
The vertical ship lift at the Three Gorges Dam in China will consist of a reinforced concrete structure with an internal steel ship chamber. The chamber will be a self-supporting orthotropic plate structure, continuously suspended from ropes with counterweights. Its components, such as segment gates, drive, horizontal guiding systems in the longitudinal and transverse directions plus locking and safety mechanisms are described here. A special procedure for reducing the tolerances of the steel components embedded in the reinforced concrete structure is explained. Continue reading →
