边坡稳定安全系数计算方法,一直采用竖直土条条分法。基于斜条分法计算的思路,根据斜土条条块力极限平衡条件,推导出边坡稳定安全系数Fs的代数表达式,取代了传统的积分或微分表达式,计算过程较为简化,收敛性能保证,只需要简单迭代即可快速得到解答。通过算例计算表明,这种方法得到的边坡稳定安全系数Fs与传统方法得到的边坡稳定安全系数Fs十分接近,证明此方法正确可行,能够方便边坡工程技术人员的掌握与应用。
Slope stability and safety factor calculation method, has been using vertical soil strip method. Based on the idea of diagonal striping method, the algebraic expression of safety factor Fs for slope stability is deduced according to the limit equilibrium condition of the strip force, which replaces the traditional integral or differential expression. The calculation process is simplified and the convergence performance Guaranteed, get quick answers with just a simple iteration. The calculation results show that the slope stability safety factor Fs obtained by this method is very close to the slope stability safety factor Fs obtained by the traditional method, which proves that this method is correct and feasible and can be used conveniently by slope engineering technicians.
