国内岩土预应力锚固技术应用及锚固技术参数统计
|
摘要
岩土预应力锚固技术在国内已广泛应用,从土、软岩到硬岩均有使用。系统搜集了国内各类大型锚固工程的技术参数,总结了国内岩土预应力锚杆(索)在锚筋材料、锚夹具及张拉设备等方面技术状况,并系统总结了岩土预应力锚固技术在大坝加固、边坡及滑坡治理、地下洞室和深基坑支护等方面的成功应用经验。
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.
