全长粘接无预应力锚杆在路堑边坡中的应用研究

Application of Fully Bonded Unstressed Anchored Bar to Cutting Slope

全长粘接无预应力锚杆具有造价低、施工方法简单、能有效地加固岩土体等优点 ,在高速公路路堑边坡中获得广泛应用。本文以广东省河梅高速公路一深挖路堑边坡为例 ,探讨了全长粘接无预应力锚杆设计中的几个问题 。

With the advantages of low cost,simplicity in construction and reliable reinforcement,fully bonded unprestressed anchored bar is widely used in the cutting slope of expressway.Several problems in the designing of the said technique are discussed herein by taking the project of Hemei expressway in Guangdong province as an example.Method of determining space of anchored bars according to slope patterns and the calculation of anchorage force based on different positions are suggested.
