【Abstract】 The prestressed anchorage technology in rock-earth, including earth, soft rock and hard rock, has been widely used in China. The technology parameters of large scale anchorage works were collected.The technology statuses of prestressed anchor-bars(cables) in aspects of anchor-rod materials, anchor clamps and tensioning instruments in rock-earth in China are presented. The successful application experiences of this technology used in dam reinforcement, slope and landslide treatments and supports of underground grottos and deep foundation-ditches are summarized.更多还原
