基于圆弧滑动面的假定，提出了一种运用模式搜索法确定边坡最危险滑动面及其对应的最小安全系数的方法，突破了传统方法在搜索最危险滑动面时必须划定圆心搜索范围的束缚，从而提高了边坡稳定性分析的可靠性。
Based on the assumption of the circular sliding surface, a method of determining the most dangerous sliding surface of the slope and its corresponding minimum safety factor by using the mode search method is proposed. It breaks through the traditional method when deciding the center of circle search range when searching for the most dangerous sliding surface. The bondage has improved the reliability of slope stability analysis.
