公路高边坡稳定性分析与加固措施研究

边坡在建设以及运营过程中,在受到降雨等外因作用时,失稳时有发生,一旦发生,轻则阻碍交通,重则危及行车安全。研究表明,南部多雨地区,针对高液限土质边坡,应在可靠截、排水措施下,进行加固设计,并设置坡面防护,可有效确保边坡长久的稳定。依托乐广高速公路K79+605~K80+160左侧边坡变更设计工程,利用Midas GTS分别建立影响因素分析模型,研究多工况下边坡的稳定性,并对加固与防护设计进行评估。

Study on Highway High Slope Stability Analysis and Reinforcement Measures

During the construction and operation of the slope,instability occurs from time to time due to external factors such as rainfall.Once it occurs,it may delay the construction period and hinder traffic,and in the end it may endanger life.Studies have shown that in rainy areas in the south,for high liquid limit soil slopes,reinforcement design should be carried out under reliable interception and drainage measures,and slope protection should be provided to effectively ensure the long-term stability of the slope.Relying on the left slope change design project of K79 +605 ~ K80 + 160 of Le-Guang Expressway,Midas GTS was used to establish the seepage and stress analysis models,the stability of the slope under multiple working conditions was calculated and analyzed,and the reinforcement measures were evaluated.
