统计过程控制在地铁穿越工程沉降监测分析中的应用
|
摘要
通过引入统计过程控制(statistical process control,SPC),建立考虑过程动态随机性的沉降监测分析方法。该方法利用统计控制图分析隧道施工引起的沉降变化是否处于稳定受控,利用过程能力指数分析沉降量大小是否满足标准要求,然后根据二者共同进行工程决策。利用所建议的方法对北京地铁8号线下穿京津城际铁路的沉降变形进行分析,从而验证该方法的可行性与优势。与传统的沉降监测分析方法相比,此方法具有如下优势:首先,SPC是对沉降演化过程动态随机性的合理分析;其次,SPC对沉降监测数据演化特性的分析更为科学;最后,SPC可以根据数据分析结果提出明确合理的工程决策措施。
In this study a settlement monitoring and analysis method considering the dynamic randomness of process is established via introducing SPC(statistical process control). This method determines whether the settlement change caused by tunnel construction is under stable control using statistical control charts and whether the settlement accords with the code using process capability index. The decision is made based on these answers.The proposed method is applied to analyze the settlement of shield construction under Beijing—Tianjin intercity railway in Beijing Metro Line 8,a vital project in the traffic construction,accordingly the feasibility and advantage of this method is verified. Over traditional methods,this method has advantages as follows. First,this method can analyze the dynamic randomness of settlement change reasonably. Then, this method can analysis the characteristics of settlement change scientifically. Finally,this method can propose the measures of engineering reasonably based on analysis for data.
