卸荷岩体锚固失效研究

介绍了边坡的分类以及在边坡支护中主要用到的支护方法。其中预应力锚索由于具有良好的工作性能而被广泛的应用在工程实践中。岩石锚固是预应力锚固技术应用中的一个重要组成部分,而其锚固效应的成败直接决定了边坡支护的成败。影响预应力锚索锚固效应的因素很多,如:岩体的应力状态、岩体岩性、锚固时间等。对卸荷岩体提出了其复杂的应力状态对锚固技术的影响。

Introduces the classification of the slope and mainly methods used in supporting of slope supporting.The prestressed an-chor cable is widely applied in engineering practice for its good working performance.The rock anchorage is an important part of the prestressed anchor technology application,however,the success or failure of the anchoring effect directly determines the slope supporting. Many factors influence the anchoring effect of prestressed anchor cable,such as,the stress state of rock mass,rock lithology,the anchoring time and so on.The effect of complex stress state of the unloading rock mass to anchorage technology is proposed.
