摘　　要：随着预应力锚固技术的不断发展,单束预应力锚索设计锚固力也在逐步提高,大吨位预应力锚固技术更广泛地应用于水利水电工程泄水建筑物闸墩建设中,使大孔径、高水头泄水闸的布置型式得到有效的发展,有利于窄河床、大泄量的泄水建筑物的布置。本文详细地介绍了广西落久水利枢纽泄水闸闸墩预应力锚索的设计及施工要求。With the continuous development of prestressed anchorage technology,the design anchorage capacity of single-beam prestressed anchor cable is gradually increasing.The large tonnage prestressed anchorage technology is widely used in the construction of discharging sluice piers of water conservation and hydropower projects,which makes it possible to arrange discharging sluices with high head and large opening,and is favorable for the layout of discharging buildings with large discharging volume on a narrow valley.A detailed introduction was made on the design and construction requirements of prestressed anchor cable for the discharging sluice piers of Luojiu Hydraulic Complex in Guangxi.
