Effect evaluation of preservative treatment in power tunnel of hydro-junction;

This article proposes two design plans for the entrance of the power tunnel of Zhangfeng reservoir on the main stream of Qin River of Zhangfeng Village of Zhengzhuang Town of Qinshui County of Jincheng City,Shanxi province,and compares their project peculiarities,analyses their construction technology and the problems that may arise in construction,and proposes the solutions to the problems.

In the paper "The Numerical Method of Diameter Selection for Hydropower Tunnel",the author has put forward a new optimization method for the selection of hydropower tunnel,and the optimal result is thought to be more proper.

Vibrating test and safety evaluation on drain cavity in Yuqiao reservoir;

This paper introduces the general situation of Hengquan Reservoir project, expounds the setting up of the orifice of intake tower of water-supply tunnel, and calculates the aerial drainage of water-supply power tunnel.

The optimization program was developed by analysis of geological conditions of different rock sections surrounding water diversion and power generation tunnel in the Xiabandi Key Water Control Project in Xinjiang.
