基于FLAC软件对超高边坡加固的稳定性分析
|
摘要
采用似圆弧状潜在滑动面模型和传递系数法对红透山铜矿工业场地超高边坡的稳定性系数及剩余下滑力和支护力进行计算。根据该边坡的茄固方案借助FlAC软件对该加固方案的稳定性进行了计算和分析,为边坡加固提供了可靠的参考依据。结果表明,该加固方案能够保证边坡的稳定,可作为类似工程参考。
Similar arc-shaped sliding surface model and the transfer coefficient are used for the stability of the coefficients and driving forces and support forces. According to the slope of the reinforcement and with FLAC software, the slope stability of the reinforcement is calculated and analysed. A reliable reference for the slope reinforcement is provided. The results show that the reinforcement to ensure the basic stability of the slope can be used as reference for similar projects.
