为有效预防和应对山体滑坡问题，利用多源监测装置实时监测边坡的变形位移情况，并通过数值模拟软件分析不同降雨工况及雨型对边坡稳定性的影响。依托云茂高速公路工程，实时采集边坡变形、降雨量和抗滑桩顶位移等数据，并结合Geo-Studio有限元软件进行数值模拟对比分析。结果表明：当降雨量达到阈值并持续一段时间后，边坡将发生突变式变形；潜在滑裂面以上的坡体位移形变量随着深度增加而逐渐减少，设有抗滑桩等加固措施的坡体变形减少速率较快；在相同降雨量条件下，短期强降雨会导致边坡安全系数迅速下降，但降雨结束后安全系数也会迅速回升；不同降雨型的影响排序为前锋型>平均型>中锋型>后锋型。
Abstract：Landslide not only causes severe property damage but also result in numerous casualties each year.To effectively prevent and respond to slope sliding issues, this paper adopts a multi-source monitoring device to monitor the real-time deformation and displacement of slopes, and uses numerical simulation software to analyze the influence of different rainfall conditions and patterns on slope stability.Specifically, relying on the Yunmao Expressway project, this study collects real-time data on slope deformation, rainfall volume, and displacement at the top of anti-sliding piles, and with Geo-Studio finite element software, conducts a comparative numerical simulation analysis.The research results indicate that when the rainfall reaches a threshold and continues for a certain period, the slope undergoes abrupt deformation, and the deformation of the slope body above the potential sliding surface gradually decreases with depth.The deformation rate of the slope body with reinforcement measures such as anti-sliding piles decreases more rapidly.Under the same rainfall conditions, short-term heavy rainfall leads to a rapid decline in the slope safety factor, while the safety factor quickly rebounds after the rain stops.The impact ranking of different rainfall patterns is as follows: front-type>average-type>middle-type>back-peak-type.
