随着城市建设的快速发展,对地下空间的利用需求急剧增长,引发的深基坑工程事故也随之增加。因此,对施工过程进行全方位的监测和变形预测分析,及时、准确地反馈基坑变形动态,对工程安全起着至关重要的作用。本文叙述了变形监测灰色GM模型预测方法,并以重庆越洋广场监测项目为例,分析基于小波变换前后的预测效果和精度水平。结果表明,灰色模型能够达到较好的应用效果。
With the rapid development of urban construction, the demand for the utilization of underground space has rapidly increased, resulting in the increase of accidents in deep excavations. Therefore, the omni-directional monitoring of the construction process and deformation prediction and analysis, timely and accurate feedback of the dynamic deformation of the pit, plays an important role in engineering safety. In this paper, the gray GM model prediction method of deformation monitoring is described. Taking the monitoring project of the Yueyang Square in Chongqing as an example, the prediction effects and accuracy levels before and after wavelet transform are analyzed. The results show that the gray model can achieve better results.
