摘要
山区高速公路路堑开挖后常形成高陡切坡,其稳定性直接关系到高速公路的畅通,为此开展高速公路高切坡的相关研究具有较重要的工程实践意义。以黔(江)—彭(水)高速公路箱子铺高边坡为例,在详细分析高边坡工程地质特征的基础上,对原有设计方案进行了优化,并通过减载、清方、放缓坡率及支挡加固等综合治理手段,保证了路堑高边坡的安全稳定,为施工期诱发的边坡失稳处治方案提供了可靠的参考依据。
High-cut slopes are formed by the excavation of depressed roads in the mountain area. Their stability is directly related to the unblocked of the highway. Therefore, it is quite important to carry out the study on the high slope in the highway. Xiangzipu High Slope in the section of Qianjiang-Pengshui highway was taken as an example in this study. Based on the detailed analysis on the engineering geological characteristics of the high slope, an optimization scheme was presented to improve the former design scheme. In addition, according to the comprehensive engineering measures, such as load shedding, cutting down, slowdown in the rate of slope and retaining reinforcement, the safety and stability of high slope can be ensured. The research can provide a reliable reference basis for control the high slope induced during the construction period.
