灰色系统理论在沉降监测预报中的应用研究

Application of grey system theory in the settlement monitoring and prediction

随着楼层的增加和沉降变形增大,文章探讨了在高层建筑物施工过程中的建筑物安全问题、变形是否超标以及未来发展趋势。当数据不完善或者数据被破坏,运用传统法已经不能够很好地模拟与预测变形的情况下,需要随时掌握建筑物信息以便采取相应的安全措施。以灰色系统理论为基础,针对建筑基础沉降的特点,建立相关的预测模型;在对已有监测数据统计分析的基础上,求出预测参数,然后根据施工进度安排,可以对不同施工期间建筑沉降进行预测,以确保施工安全。

This paper discusses building safety issues and whether deformation will be excessive, as well as future trends with the increase in floor and settlement deformation in the process of constructing high-rise buildings.When the data is incomplete or destructed and using traditional method cannot fully simulate and predict deformation, we need to keep abreast of information in order to take appropriate safety measures.Based on grey system theory and in view of the characteristics of settlement of the building, we establish relevant forecasting model, and calculate prediction parameters based on statistical analysis of existing monitoring data, and then forecast building settlement of different construction periods according to the construction schedule, in order to ensure construction safety.
