文献[1]采用解析几何方法推导出圆弧法滑弧几何参数的解析解公式,并得出了较好的结果。但文献[1]的解析解是以36°法为基础。实际边坡稳定性验算中,4．5H法在重要边坡中使用更多,精度也更好。本文参照文献[1]的求解方法,以4．5H法为基础重新推导出圆弧法滑面几何参数的解析解。多种算法算例对比表明,改进算法的计算结果更为合理。
Literature [1] uses analytic geometry to deduce the analytic solution of geometric parameters of arc-based arc-smoothing, and obtains better results. However, the analytical solution of [1] is based on the 36 ° method. The actual slope stability check, 4.5H method used in more important slope, the accuracy is better. In this paper, the method of reference [1] is used to re-derive the analytic solution of geometric parameters of the arc-based sliding surface based on 4.5H method. Comparison of a variety of algorithms shows that the improved algorithm is more reasonable.
