摘要
为揭示黄土路堑边坡在施工及运营过程长期演化规律,选取吉河高速公路某典型黄土路堑边坡作为研究对象,采用数值分析和现场监测相结合的研究手段。布设监测断面,以路基沉降和坡脚侧向位移为主要监测参数,对边坡变形规律进行长期跟踪监测,并对边坡开挖前后的稳定性进行对比分析。监测数据和分析结果很好地指导了黄土边坡施工,揭示了黄土边坡变形演化规律。
In order to reveal the long-term evolution law of loess cutting slope in construction and operation process, taking a typical loess cutting slope of Jibe Highway as the research object, using the numerical analysis combined with the field monitoring as the research methods, this paper laid the monitoring section. Taking the subgrade settlement and lateral displacement of slope foot as the main monitoring parameters, it had the long-term tracking and monitoring of slope deformation laws and also compared and analyzed the stability of slope before and after the excavation. The monitoring data and analysis results could guide the construction of loess slope and reveal the evolution law of loess slope deformation.
