预应力锚索在边坡工程中的应用

Pre-stressed Anchor Wire Method and its Applications in Slope Engineering

预应力锚索作为高危边坡加固的一种有效措施,在各种边坡工程建设中得到了广泛的应用。本文首先阐述了道路工程高路堑边坡预应力锚索施工的工艺特点、施工工艺及施工要点,提出了常见问题的处理措施。基于锚索预应力损失问题是关系到锚固工程安全与否的重要因素,随后对预应力锚索加固边坡的机理、锚索预应力损失的影响因素及其应对方法进行了探讨,提出了应力补偿的措施。

Pre-stressed anchor wire is widely used in slope engineering as an effective measure of slope reinforcement. This paper expounds the technical features, construction process and construction points of the pre-stressed anchor wire construction technique for the slope engineering, and some control measures are given. Based on the pre-stress loss of anchor wire is a vital factor which can affect the safety of anchoring project, the mechanism of slope reinforcement, influence factors of pre-stress loss and the at last the methods for compensating the stress loss are put forward .
