摘要
本文介绍了链子崖危岩体治理重点单元一＂五万方＂危岩体预应力锚索加固工程施工方案。在锚固设计中，推荐了１０００ｋＮ、２０００ｋＮ和３０００ｋＮ三种预应力锚索，并给定了相应的锚索参数和施工方案。五万方危岩体现今稳定性极差，因此，锚索的张拉顺序及锁定锚固力的大小关系到锚固工程的成败，本文对这一问题进行了探讨。
The controlling engineering for the Lianziya Dangerous Rockmass in the Three Gorges of the Yangtze River have been conducted. The paper introduces constructing programme of the dangerous rockmass controlling and the anchoring engineering. For the key part of the rockmass, called 'Wuwargfang' dangerous rockmass, the anchoring is divided into eight zones and about 200 cables are fixed of 1000kN, 2000kN and 3000kN. The cable parameters are designed, and the technique and monitoring programme are recommended.
