摘要
结合隰吉高速公路深挖路堑施工与变形监测实践,根据监测结果分析边坡稳定性。结合深挖路堑实际情况,制定施工方案,开展路堑开挖和边坡防护。分别布置测点和钻孔测斜仪,对路基边坡地表位移和深部位移开展监测,分析监测结果得出施工后边坡变形逐步趋稳,现场未发现边坡出现明显变形破坏,边坡稳定性良好。
Combining the practice of deep cut construction and deformation monitoring of Xiji Expressway,the slope stability is analyzed based on the monitoring results.Combining the actual situation of deep excavation road cutting,formulate construction plan,carry out road cutting excavation and side slope protection.The measuring points and borehole inclinometer were arranged to monitor the surface displacement and deep displacement of the subgrade slope.Analysis of the monitoring results showed that the slope deformation gradually stabilized after the construction.No obvious deformation or failure of the slope was found on site,and the slope was stable and good.
