摘要

2005年6月下旬广东河源地区遭遇百年一遇的强降雨袭击，累积降雨量超过1 000 mm。强降雨诱发了边坡的非稳定变形。基于加卸载响应比理论，分析了粤赣高速公路k2路堑高边坡的内、外部变形及加固结构的响应比，讨论了边坡的变形及其稳定性。采用有限元法计算了降雨后支护和不支护两种工况的边坡变形，对k2边坡的加固效果进行了科学评价。研究表明：边坡在强降雨条件下支护后的边坡变形速率趋于稳定，k2边坡加固能够满足稳定性设计要求。

Abstract

A storm attacked the Heyuan area late June

2005. The rainfall exceeded 1 000 mm. The storm triggered the unstable deformation of the k2 slope. Based on the Load/Unload Response Ratio theory

the deformation and stability of the slope are discussed by analyzing the response ratio of inner deformation

outer deformation and the reinforced structure of k2 high cut slope. The slope deformations on support and without support structure under the storm are analyzed by using finite element method

and the effect of the slope reinforced structure is assessed. The deformation ratio of the slope trends stable under the storm after reinforcement. k2 slope reinforcement can be met the stability of design standards.
