摘要传递系数法是我国独创的计算下滑推力的极限平衡分析方法，因计算简便实用在边(滑)坡防治工程中得到广泛的应用，但该方法对相邻滑块夹角大于10°的复杂滑体有其局限性，计算结果误差通常较大。在边坡下滑方向的基础上，边坡下滑推力不再沿条块底滑面传递，而是沿着边坡下滑方向进行传递，提出一种改进的传递系数法。圆弧型及缓倾折线型滑面边坡算例结果表明：本文方法较严格极限平衡M-P法安全系数误差最大为3.73%，下滑推力曲线与规范传递系数法完全吻合，验证本文方法在常规情况下边坡稳定性分析中的合理性。复杂折线型滑面算例结果表明：规范传递系数法与本文方法相对M-P法安全系数的误差分别为21.66%，6.83%，且本文方法下滑推力整体上略大于规范方法结果。可见，本文方法适用于复杂滑坡体下滑推力的确定，可作为规范传递系数法的一种扩展和补充，为边(滑)坡防治工程提供有效设计依据。

Abstract：The transfer coefficient method is the original limit equilibrium method of analysis utilized in China for calculating the sliding thrust force of landslide. Due to its straightforward and pragmatic calculation，it finds extensive application in landslide prevention and treatment engineering. However，this method exhibits limitations for complex sliding bodies with an angle greater than 10° between adjacent slices，often resulting in significant calculation errors. Based on the sliding direction of slope，the slope sliding thrust can be transferred along the sliding direction rather than along the bottom of the slices，and the improved transfer coefficient method was proposed. The calculation results of a landslide with a circular sliding surface and a landslide with a gently tipping polyline sliding surface indicate that the proposed method exhibits a safety factor error of 3.73% when compared to the strict limit equilibrium M-P method. Additionally，the curves for sliding thrust of the proposed method are completely consistent with those of the transfer coefficient method，and its curve of the angle for sliding direction is gentler than the standard method，which verifies the rationality of the proposed method in conventional slope stability analysis. Furthermore，the analysis results of a landslide with a complex polyline sliding surface indicate that，the error of safety factor between the transfer coefficient method and M-P method is 21.66%，while the relative error is 6.83% for the proposed method. Moreover，the sliding thrust of the proposed method is slightly greater than that of the standard method. These findings demonstrate that the proposed method is suitable for determining the sliding thrust of the complex landslide，which can be used as an extension and supplement of the transfer coefficient method，providing an effective design basis for landslide prevention and treatment engineering.
