摘要
本文首先介绍一种加固高拱坝的高效方法—垫脚加锚法 ,并阐述预应力锚索的锚固机理 ,然后对李家峡拱坝的垫脚加锚布置作了介绍。
An effective reinforcement method of abutment anchorage for high arch dam is introduced, and anchoring mechanism of pre stressed tendon is expounded. Then, the arrangement of abutment anchorage of Lijiaxia arch dam is presented. Both the geomechanical model test and nonlinear 3 D finite element analysis for Lijiaxia arch dam with or without abutment anchorage show that abutment anchorage has good reinforeement effect for high arch dam.
