浙江省山区水利枢纽工程水闸消能防冲新技术

摘要

Based on investigation of construction and operation conditions of hydropower projects in the mountainous area of Zhejiang Province, the problems of energy dissipation and structure scour prevention were analyzed, and some new materials and technologies are proposed, such as fiber reinforced concrete ( FRC) , the stone cage net, and riprap concrete. Application of these new technologies shows that they can reduce temperature cracking during the construction period and improve the abrasion resistance after use of FRC. The capability of the weak part of the riprap anti-scour trench is effectively improved after using the stone cage net and riprap concrete.%在调查浙江省近年来建设的山区水利枢纽工程的建设及运行情况的基础上,分析消能防冲结构存在的问题,研究相应的保护或加固技术,介绍消能防冲结构中纤维混凝土、石笼网、抛石混凝土等新材料、新技术的应用情况和适用条件.调查结果表明,闸底板及消力池底板表面采用纤维混凝土后,施工期温度裂缝明显减少,耐磨损性能有所提高,石笼网和抛石混凝土技术可以有效地提高抛石防冲槽等结构薄弱部位的抗冲能力.
