二元结构边坡是指上部为土层、下部为基岩的一类边坡,其破坏模式通常为上覆土层沿土-岩界面或风化层界面发生滑动。由于边坡各部位坡度、上覆土层厚度的差异,导致边坡潜在滑面上的应力状态具有差异性,研究其滑面上的应力分布规律对优化边坡加固方案具有重要意义。本文以某桥梁边坡为例,采用点安全系数法对其土-岩界面上的点安全系数分布进行分析研究。结果表明,该边坡在原加固方案下具有较好的稳定性,但支护量较大。基于土-岩界面点安全系数分布的优化加固方案不仅能满足边坡稳定性需求,同时减少了工程数量,降低了工程造价。

Binary structure slopes refer to a type of slope where the upper part consists of soil layers and the lower part consists of bedrock. The failure mode of such slopes usually involves sliding along the soil-rock interface or the weathering layer interface. Due to variations in slope gradient and the thickness of the overlying soil layer,the stress distribution on the potential sliding surface of the slope differs in different sections. Studying the stress distribution patterns on the sliding surface is of crucial significance for optimizing slope reinforcement schemes. In this study,a bridge slope was taken as an example,and the point safety factor method was used to analyze and study the distribution of point safety factors along the soil-rock interface. The results showed that the slope exhibited good stability under the original reinforcement scheme but required significant support. The optimized reinforcement scheme based on the distribution of point safety factors along the soil-rock interface also met the stability requirements of the slope,while reducing the amount of construction and lowering costs.
