摘要
通过研究给出了一种盾构机PLC记录数据的数据挖掘方法。以上海轨道交通14号线某盾构机推进土仓压力为研究对象,计算给出了该区间土仓压力的分布形态。通过观察分析土压力统计分布特征,将整个隧道样本区分为非承压水地层样本和承压水地层样本,分别给出了这两种形式下的土压力统计特征。
A data mining method is presented,which adopts programmable logic controller(PLC)to record data of shield machine.The earth pressure in excavation chamber of a shield machine of Shanghai Rail Transit Line 14 is taken as the object;the distribution pattern of earth pressure in excavation chamber in this interval tunnel is given by calculation.By observing and analyzing the statistical distribution characteristics of earth pressure,the interval tunnel is distinguished into unconfined water formation sample and confined water formation sample.And the statistical characteristics of earth pressure of these two samples are given respectively.
