摘要: 我国很多大坝为二十世纪50、60 年代兴建的,三类坝情况十分严重。在混凝土坝中,基岩断层裂缝对结构安全构成严重威胁,工程实例说明,预应力锚固和止滑重力墩以及高压固结灌浆不失为基岩断层裂缝补强加固的有效措施。本文简述了预应力锚固的施工方法和程序。
Abstract: A lot of dams in China were built during 1950~1970. To concrete dams, the bedrock fault crack is a big threat to dam safety. In the paper, successful application of prestressed anchorage, anti-slide gravity pier and high pressure consolidation grouting in dam bedrock fault crack treatment was introduced. As well, the constitution of prestressed anchorage and construction process were illustrated.
