预应力锚梁的设计研究

预应力锚梁是岩质边坡加固的一项新技术,具有排水、监测、补强等一般锚固洞不具有的功能。但预应力锚梁的设计尚没有较好的办法。文章将判别边坡稳定的不平衡推力法和预应力结构设计的方法有机结合起来,较好的解决了预应力锚梁的设计荷载、预应力对边坡稳定的贡献以及和锚梁结构的设计强度等问题,为预应力锚梁的设计提供了一种设计方法,对这一新技术在工程中的的应用提供了设计上的依据。

STUDY ON THE DESIGN OF PRESTRESSED ANCHORING BEAM

Although prestressed anchoring beam is a new technique for rock slope reinforcement and has some functions, such as drainage, monitoring and reinforcement, which ordinary anchoring cavern hasn't, it still hasn't better design method now. In the paper, the author combined the method of imbalance thrust force with the design of prestressed structure to solve not only slope stability analysis affected by design load and prestressing force of prestressed anchoring beam but also the design strength of anchoring beam structure. The new technique provides a kind of design method to prestressed anchor beam and provides design basis for application of the new technique in the engineering project.
