摘要
深路堑边坡的核心设计要素是边坡稳定,深路堑边坡的设计方案和防护措施直接决定了深路堑边坡的稳定性。边坡稳定分析中,通过安全系数来衡量边坡的稳定性,并采取相应的边坡防护措施,因此边坡的安全系数取值大小对边坡安全、工程效益有直接的影响。结合阿尔及利亚175铁路项目深路堑边坡,模拟边坡的圆弧滑动破坏并确定破坏滑移面,计算安全系数最小值,与安全系数标准值相比较,进行短期稳定、长期稳定和地震作用下的稳定分析,以保证边坡稳定性和选择合适的支挡方案。
The most important element of design for the deep cutting slope is the stability, which is directly determined by the design scheme and the protective measures of deep cutting. The factor of safety is adopted to evaluate the stability of side slope and to choose the measures of protection, so the value of safety factor has the direct influence on the security of the side slope and the project efficiency. In order to ensure the stability of side slope and to choose the appropriate retaining alternative, the minimum safety factor and the normal safety factor is compared with the analysis of the stability in short- term, long-term and under-earthquake condition through simulating the damage of circular slide and determining its dam- aged surface based on deep cutting slope of Algeria 175 Railway Project.
