基于时间序列和灰色模型的大厦基坑监测

Building Foundation Pit Monitoring Based on Time Series and Grey Model

如何科学、实时、准确地分析基坑变形是现代工程测量中的一项重要内容。以某大厦基坑为例,将现场工作情况与查阅资料相结合,对基坑的支护桩顶水平位移与沉降、周边道路沉降、地下水位、深层水平位移等项目进行了监测,分析了基坑水平位移与沉降的变化规律,并对可能发生的变化进行了预测。结果表明,基坑监测为基坑安全施工提供了可靠保障,该基坑监测设计方案和分析过程合理可靠。

How to analyze the foundation pit deformation scientifically,in real time and accurately is an important content in modern engineering survey.Taking a building foundation pit for example,combining the field work situation with the reference data,we monitored the foundation pit supporting pile top horizontal displacement and settlement,the settlement of surrounding roads,underground water level,the deep horizontal displacement,analyzed the change rules of foundation pit horizontal displacement and settlement,and predicted the possible changes.The result shows that the foundation pit monitoring provides a reliable guarantee for the foundation pit safety construction,and the design scheme and analysis process of foundation pit monitoring are reasonable and reliable.
