基坑工程测斜数据挖掘与安全分析探讨

在工程隐患发展成工程事故之前,监测数据往往存在异常反应,此时若采取相应措施,就能以很小的代价降低工程风险。但在采用何种指标来评判工程存在的危险上一直存在争议。以上海近年来基坑工程的大量监测数据为基础,通过数据挖掘方法寻找工程风险和测斜数据之间的联系和存在的规律,以形成量化的评判指标来评价工程的危险程度,从技术角度提供了一个进行安全分析的办法。

Data Mining Achievement of Pit Excavations and Safty Analysis

Before the hidden trouble becomes an accident in a project, some obviously abnormal responses of the survey data should be found, thus, the project risk can be reduced with less expenses. Meanwhile, there are fierce debates on which measure shall be chosen to define the degree of project risk. Based on massive monitors' data of the recent excavation projects in Shanghai, through the data mining method and the measuring of the slanting data,this paper seeks to find the relation and the existence rule between them,then uses the quantitative judgment target to appraise the degree of project hazard,so as to provide a control means in technical way.
