Closure gate design for diversion tunnel of Xiaorongjiang Hydraulic Complex;

Sanzuodian hydraulic complex locates at the downstream of the influent Yen river of Xiliao river in Chifeng city, Inner Mongolia, which is the key project for flood control and water supply for the city in the basin plan of Songhua river and Liao river, which main task is to improve the flood control and water supply standard where locates at the distance 35Km from hydraulic complex.

Study on coupling of 3D visualization with numerical simulation for powerhouse excavation of a certain hydro-junction;

Discussion on seepage prevention of deep overburden layer ofXiabandi hydro-junction in Xinjiang;

Video monitoring system has been widely applied in safe production monitoring for hydro-junction, and gradually developed from traditional security monitoring to management monitoring.

Based on analyzing affecting factors of the designed lowest navigable stage, the problem of calculating the designed lowest navigable stage at downstream stretch of hydro junction is generalized as a nonlinear functional relation between input and output.

In this paper, achievements gained in conservating soil and water conservation plantation in Wanjiazhai hydro junction region have been introduced.

Engineering geological problems of Xiaoliangdi key water control project Yellow River and their disposal measures;

Hydrofracturing insitu stress mesasurements of three boreholes in Wanjiazhai key water control project have been carried out.

The reasonable share of investment in a key water control project is the base to calculate the profit correctly.
