预应力锚索技术在公路高边坡工程中的应用

我国公路建设的范围不断拓展,技术不断进步,预应力锚索技术日趋成熟和完善,在高边坡工程中有着良好的应用。传统的挡土墙以及护面墙等高边坡工程工艺存在着一定的缺陷,施工效率不高,由于高边坡工程总量大,地质状况多变,所以,应用预应力锚索技术能够很好地提高工程的稳定性和质量。本文就预应力锚索技术在公路高边坡工程中的应用进行了详细的讨论。

Stability evaluation and protection of slope for Laosongling-Yanji Highway

The authors analyzed the engineering geological characteristics of the slope of the study area (K75+840-K76+340). Two typical cross-sections have been chosen to analyze the failure modes after the excavation of the highway. Different types of the failure modes have been calculated and analyzed. The results show that some dealing methods have been advised to ensure the stability of the slopes.
