盾构隧道变形监测传感器的鲁棒性布设方法
Robust sensor placement method for deformation monitoring in shield tunnels
摘要
Abstract
In response to the issues that deployment of monitoring sensors relies on the experience of on-site engineers and lacks theoretical basis,a robust deployment method based on information theory was proposed.This method mainly includes five steps:structural mechanics model of shield tunnel,random modeling of lining load,probability distribution calculation of structural deformation,deformation information entropy calculation,and optimization of layout plan based on information entropy.Taking a diameter shield tunnel under symmetric loads as an example,the implementation process of the proposed robust deployment method was explained.The study found that the coefficient of variation and correlation of lining load have a significant impact on the size of deformation information entropy,but have no significant impact on the distribution pattern of information entropy.The tilt sensor placement scheme under asymmetric loads was illustrated through real monitoring data from the tunnels of Shanghai Metro Line 12.关键词
