基于灰色理论的深基坑变形监测分析
|
摘要
为了能更好控制深基坑开挖过程中周边环境变形,为城市深基坑施工提供保障,本文在灰色理论基础上,通过建立深基坑变形预测模型,对大学城地铁车站进行控制桩水平位移和沉降实时监测。结果表明:灰色理论应用到深基坑变形监测数据分析上是可行的;灰色预测模型能很好的反映深基坑变形监测数据的发展趋势;水平位移和沉降监测结果反应出来的深基坑周边变形情况基本一致。
In order to better control the surrounding environment deformation during excavation of deep foundation pit and provide guarantee for the construction of deep foundation pit in the city, based on the grey theory, this paper established a deep foundation pit deformation prediction model, and conducts real-time monitoring of the horizontal displacement and settlement of the university city subway station. The results show that: it is feasible to apply the grey theory to the deformation monitoring data of deep foundation pit; the grey prediction model can reflect the development trend of deep foundation pit deformation monitoring data; the deformation of deep foundation pit of horizontal displacement and settlement monitoring results is basically the same.
