摘要
在大型工程建设中,需要对建筑物及邻近建筑物进行变形监测,本文以天津市某基坑开挖对建筑物影响的监测数据处理为例,介绍了灰色系统模型的基本原理,通过采用传统的GM(1,1)灰色模型和非等步长GM(1,1)灰色模型两种方法对监测数据进行处理,对模型的预测效果进行了分析。
There need for deformation monitoring in the large-scale construction projects.in this paper,take deformation monitoring to adjacent building impact of the excavation for example.The basic principle of Grey system model are introduced,the traditional GM(1,1) model and unequal-step GM(1,1) model are applied to process data of deformation monitoring,the result of subsidence prediction are analyzed.
