摘要
分析了公路边坡破坏形式和影响边坡稳定性的主要因素;以某山区高速公路项目为研究对象,利用理正岩土软件中的不平衡推力法计算了未加固的边坡在不同工况条件下的安全系数;提出采用预应力锚索框架梁方案提升边坡稳定性,计算了不同锚固长度和锚索倾角条件下的安全系数。
The failure forms of highway slope and the main factors affecting the stability are analyzed;taking a mountain expressway project as the research object,the safety coefficient of the unreinforced slope under different working conditions is calculated by using the unbalanced reasoning method in the Lizheng Geotechnical software;the prestressed anchor cable frame beam scheme is proposed to improve the slope stability,and the safety coefficient under the conditions of different anchor length and anchor cable inclination is calculated.
