为了总结新型组合式消能工在高坝建设发展中的可利用性及重要性,综述了收缩式消能工与其他消能工联合运用的结构、原理和工程应用.收缩式消能工由于其水流占用宽度较小等特点,与其他消能工联合运用可以解决许多在深狭河谷中修建水利枢纽的泄洪问题.根据不同工程自身的特点,应设计和选用不同的组合式消能方式.
The availability and importance of new combined types of energy dissipators in the construction of high dams were studied. The structures, principles and applications of contraction energy dissipators combined with other energy dissipators were reviewed. Due to the contraction characteristics of contraction energy dissipators, the combined energy dissipators can be used in flood discharge of hydropower projects constructed in deep and narrow stream valleys. It is crucial to design and use different combined types of energy dissipators according to different characteristics of projects.
