摘　　要：山区高速公路顺层岩质深路堑路段,岩体经过较大的施工开挖及雨水浸渗后,往往容易产生顺层滑坡,预应力锚杆加固边坡通常是解决岩体顺层滑动的有效措施。结合工程实例对锚杆的布置、锚固段长度等进行分析,对预应力锚杆锚固边坡设计施工有一定的指导意义。Deep after they are cutted of anchor placement, cutting slopes are easy to slide in the direction of rock slope and soaked, prestressed anchor is a good measure to solve the struction of prestressed in mountainous areas problem. The analysis designation and construction of prestressed anchor.
