一、消能型式的选择太平哨电站主坝坝高30余米,最大坝高44.0米,属于中等高度的坝。溢流坝具有单宽流量较大,坝下游水位变化幅变较大等特点。就一般消能型式,即底流、挑流和面流而言,都有实施的可能。消力池底流消能型式,理论比较成熟,经验也比较多,只要设计适当,是安全可靠的。但护坦工程量太大,且干扰主坝施工。挑流消能和面流消能均
First, the energy-saving type of choice Taiping Sentinel Dam main dam more than 30 meters high, the maximum dam height of 44.0 meters, belonging to the dam of medium height. Overflow dam with a single wide flow, dam downstream changes in the larger changes in water level and so on. In terms of general energy dissipation patterns, that is, underflow, pick-off and surface flow, there is a possibility of implementation. The energy dissipation mode of the bottomless flow pool is relatively mature in theory and has more experience. As long as the design is proper, it is safe and reliable. However, escorting the project is too large, and interfere with the construction of the main dam. Digestion and energy dissipation surface flow are
