The Limit Crack Analysis of Hydraulic Tunnel Lining Structure
There are many results about the limit crack analysis of hydraulic tunnel lining structure, but the calculation of crack width is based on the pull-out test of the ordinary reinforced concrete,and the truth is neglected that lining and rock are united bearing body.Therefore experimental and theoretical studies are needed about the role of rock on [...]
Research on Joint Energy Dissipation of Ski-Jump with Hydraulic Jump
“Big discharge,tall water head and narrow canyon” have been the characteristics of water power exploitture,which denotes the difficulty of water power exploitture is increaseing,also brings challenging problem to research of flood discharge and energy dissipation.Based on analysis of traditional energy dissipator and making use of their virtues, this paper advances a new type energy dissipator [...]
Seismic Response Primary Analysis on Underground Rock Tunnel for Hydropower Station
The response and safety of rock tunnel under earthquake are the difficulties and hot pots for construction of hydraulic engineering in the intensive earthquake area of West China.It has strategic meaning that how to assuring the tunnel working well during earthquake.To analyse the seismic response on underground rock tunnel for hydraulic station,this paper briefly describes [...]
3-D Finite Element Analysis of CFRD Used in Pumped-Storage Power Station
The concrete faced rockfill dam(CRFD) has become one of the most economical dam types.With the rapid development of pumped-storage power station,more and more concrete faced rockfill dams are used in pumped-storage power station.In order to increase the capacity of pumped-storage power station,the axis of the concrete faced rockfill dam is usually convex to the outside [...]
Cause Analysis and Reinforced Structure Safety of Cracks of Concrete Piers of Overflow Dam
It is a common phenomenon that the piers of dam of power plant appear cracks,especially in the northeast of China,few concrete gravity dams appear cracks during the construction period in pier,however,some cracks appear while many dams run many years,such as cross-cutting cracks,which have seriously affected the normal operation of power plant.The main reasons of cracking [...]

Study on the Dynamic Numerical-Model and Boundary of Underground Hydropower House under the Action of Internal Dynamic Loadings
With the development of the hydro-electrical enterprise in China,the scale of the hydropower station is increasing and its importance is also becoming more and more significant.In the meantime,the safety issue of the hydropower station has also been drawn more attention.As an important constituent part of the power station;the powerhouse, especially the underground powerhouse of the [...]
Research and Application of Real-time Water Level Control after Interbasin Water Transfer
Inter-Basin Water Transfer Project is not only huge investment,but also complex system.,which make the decision higher demand.Whether or not the decision is reasonable related to the inter-basin project’s operation and safety as well as the probability of realizing the value,water transfer decisions should be carefully studied in both planning and running period.So far,researchers paied much [...]
Field Test and Numerical Simulation Analysis of Influence of Blasting Vibration on Adjacent Chamber
It’s inevitable that blasting construction will have an adverse effect on the safety of underground chamber. The side wall of adjacent chamber will have tensile stress and shearing stress when blasting seismic wave reach the border of side wall of adjacent chamber. For those underground chambers with small clear distance and large section in blasting [...]
