Hydraulic tunnel according to the functions of flood discharge, water diversion, irrigation, water supply, and the construction diversion tunnel of desilting emptying. Nowadays, water conservancy project on flood discharge runnel design requirements more and more high, so the factors taken into account the amount of spillway tunnel engineering, engineering cost, structure design and other factors to evaluate nature of the spillway tunnel is very important. Therefore, in actual construction, of spillway tunnel of optimization design, whether from the economic point of view, or from the point of view of safety and applicability are necessary. This article mainly from the overall layout of flood discharge tunnel, structure design and so on, and then discuss the optimization scheme.展开更多

It is currently an important task of ideological and political education, guided by ＂Long-term Education Reform and Development Plan＂, to recognize the importance and complexity of the ideological and political education environment, and actively respond to challenges of the changing domestic and international environment, continuous optimization of ideological and political education environment.展开更多
