基于GM(1,1)模型的高速公路边坡稳定性研究

Study on the stability of highway slopes based on GM(1,1) model

目的由于气象、地形及施工条件等的影响,高速公路边坡可能会发生滑塌,造成巨大的危害。针对边坡稳定性问题,分析边坡稳定性的影响因素。方法以现场边坡监控数据为依据,运用灰色预测GM(1,1)模型进行边坡稳定性预测。结果研究结果表明模型预测值与实测值误差较小,采用该预测模型可为技术人员提供数据支持,并根据所预测的结果来采取必要的安全措施以保证边坡的稳定性。结论灰色理论的运用和必要的监控对于确保边坡安全具有重要的指导意义。

ObjectivemTo analyze the influence factors of slope stability because the highway slopesmay slump and cause great harm to the resident with the impact of weather, terrain and constructionconditions. Methods--Based on the monitored data of slopes, the gray forecast model was applied tostudy the stability of highway slopes. Results--The research results show that the difference betweenthe predicted values and the measured values is small, which can provide data support to technicians,and according to the predicted results, the technicians can take some necessary security measures toensure the stability of slopes. Conclusion--The use of grey theory and the essential monitoring have animportant guiding significance to ensure the security of the slope.
