喷锚网加固技术在合徐高速公路路堑高边坡工点的应用

Application of Supporting Technique of Anchored Network Structure with Sprayed Concrete for High Cutting Slopes in Hefei-Xuzhou Expressway Project

由于受地形及路线平纵线形的限制,有些高等级公路会出现较大的路堑段。对于这些路段应作为工点进行单独设计,其中如何做好路堑段边坡设计以尽可能地消除或抑制各种病害并改善道路景观尤为重要,喷锚网加固技术即为常用的方法之一,故就其施工方法作一介绍有一定的实用价值。

With the limit of the topography and horizontal-vertical alignment, it appears high cutting slope in some expressway and needs to design for these places respectively. How to makes the design of high cutting slope well, how to do our best to avoid or control all kinds of dangers, how to improve the road landscape are very important in design. The method of anchored network for reinforcement is often be used, and it is practical to introduce its technique.
