摘要
龙滩水电站边坡地质条件复杂,进水口边坡最大坡高达420m,为保证左右岸高边坡的整体稳定和工程的长期运行安全,左右岸边坡加固支护中采用了1000kN、2000kN和3000kN级预应力锚索,来提高边坡的整体稳定性。论文主要介绍了预应力锚索的设计、构造及张拉程序等。
Considering the 420m intake high slope and complicated geological conditions at the right bank of Longtan project, pre-stressed anchorage cables of 1 000 kN, 2 000 kN and 3 000 kN grades are adopted for reinforcement support so as to ensure the integral stability of the slope and the long-term safe operation of the project. This paper introduces the design, structure and tension control of the pre-stressed anchorage cables.
