丹江口大坝加高工程闸墩预应力锚杆加固技术

Gate Pier Pre-stressed Anchor Rod Reinforcement Technology of Danjiangkou Dam Heightening Project

丹江口水库大坝加高工程是南水北调中线水源工程,此次丹江口大坝加高工程闸墩预应力加固,对大坝10个坝段和20个闸墩进行预应力加固。本文主要介绍了丹江口大坝加高工程闸墩预应力锚杆加固的施工技术。锚杆测力计的观测数据表明,预应力锚杆施工满足设计要求。

Danjiangkou Reservoir Dam Heightening Project belongs to South-to-North Water Diversion Midline Water Source Project. Pre-stressed reinforcement is conducted on 10 dam sections and 20 gate piers on the dam during gate pier pre-stressed reinforcement of Danjiangkou Dam Heightening Project. Construction technology of gate pier pre-stressed anchor rod reinforcement of Danjiangkou Dam Heightening Project is mainly introduced in the paper. Observation data of rock bolt dynamometer shows that pre-stressed anchor rod construction can meet design requirements.
