摘要: 为提高瑞典条分法的工程分析效果,通过三角函数积分得到均质边坡稳定系数解析式,将该积分式用于边坡分析,不仅可以节省计算工作量,还可以得到瑞典法精确解;为了解决目前边坡滑面搜寻方法的不足,提出了通过搜寻圆弧在坡顶面的截距和圆弧半径来确定出最危险圆弧面,该方法不仅能减小搜寻用时,还能保证滑面追踪的准确性。

Abstract: In order to enhance the engineering analysis effect of the Sweden slices method, the circular function integration has been used to get the analytical formula of stability coefficient for a homogeneous slope. Applying this integration formula to analyze slopes, the amount of calculation will be saved and the most accurate result can be got. In order to resolve the shortcoming of current method, an improved method was put forward, according to which, the most dangerous circular surface can be confirmed through searching the circular arc’s intercept on the slope’s top face and radius. The improved method can not only reduce the searching time but also guarantee the success to track the dangerous sliding surface.

Key words: geotechnical engineering, Sweden slices method, circular function integration, coefficient of stability, analytical formula, the most dangerous sliding surface
