云南元江边坡预应力锚索地梁设计与施工

Pre-stressed anchor rope ground beam design and construction of slope in Yuanjiang,Yunnan Province

云南元磨高速公路全长147km,道路施工后,滑坡、坍塌、崩塌现象甚多,边坡治理迫在眉睫。预应力锚索地梁加固边坡技术是近年来发展起来的一门应用技术,它具有造价低廉,施工简便,受力可靠等优点,是一项主动性加固边坡技术,在治理山体滑坡坍塌路段有较强实用价值。本文主要介绍预应力锚索地梁设计施工工艺及其施工工法和在高陡边坡滑坍地段加固实例及应用。

The length of Yuanjiang expressway in Yunnan Province is 147km.After construction,many landslide sand collapses have taken place there,so the slide slope control is very urgent.Using prestressed anchor rope to reinforce slide slope is an application technique that has developed in recent years.This technique has many advantages,such as low cost,simple construction and the reliability of bearing force.It is an initative technique to reinforce slide slope,which has more practical value in controlling collapse and landslide.This paper mainly introduces the design and construction technique of prestressed anchor rope ground beam,as well as the practical example and application of the reinforcement in collapse high slide slope.
