摘要
预应力锚固技术的最大特点,是尽可能减少被锚固的土体或岩体的扰动,并通过锚固措施合理地提高可利用岩体或土体的强度。预应力锚固技术是最高效的和最经济的加固技术。长江三峡库区是滑坡、崩塌等环境地质灾害高发区,目前大吨位长锚索已广泛应用于滑坡治理工程中,本文就三峡库区某滑坡治理工程1000kN级长锚索的安全施工方法进行总结与探讨,为今后同类工程的安全施工积累经验。
The most important feature of prestress anchorage is to decrease the disturbance of the fixed soil or rock body and promote the intensity of soil and rock body by anchorage, so the prestress chahorage technoogy is the most efficient and economical way. Enviornment geologic harzards such as landslide or collapse frequently happen in the reservoi area of the Three Gorges. Now the huge-tonnge long anchorage is applied widely in landslide control projects. This paper gives a primary discussion and summary of the safety constructirn method about the long anchored cables of 1000kN rank used in one landslide control project in the reservoi area of Three Gorges, hoping to help accumulate some experience of safety construction for the similar projects later.
