摘要
在对压力型预应力锚索机理进行介绍的基础上,结合工程实例,对压力型预应力锚索的设计与施工工艺进行了较为详细的论述。实践证明本工程锚索设计合理,施工成功,工程安全可靠,压力型预应力锚索技术作为一种先进的手段,解决了高边墙地下洞室工程支护问题。
On basis of introducing the mechanisms of the pressure pre-stressed anchoring cables, the authors, taking case history as example, expatiate on the design and construction technology of pressure pre-stressed anchoring cables in detail. The practice proves that the design of the anchoring cables of the case history is reasonable, the construction of the anchoring cables is successful and the works is safe and reliable. By means of pressure pre-stressed anchoring cables, which are a kind of advanced technology, the problem of reinforcement of underground caverns with high side walls has been successfully solved.
