摘要
不张拉锚索是一种新的大吨位的深孔被动加固措施,要求在开挖分层面上实施,在后期下挖过程的岩体变位中即可受力而发挥作用。在初步研究的基础上,已在李家峡工程中采用,并经受了检验,初步收到了工程实效。
Non-tension anchorage cable is a new stabilized method with large tonnage for deep holes. It requires implementing on the excavated layers, and is tensioned and effective during the downward excavation process at later stage. On a basis of preliminary study, it has been used in the Lijiaxia Hydropower Station subject to the verification, and it has initially achieved practical effect.
