Real time monitoring method for the longitudinal settlement of shield tunnel using wireless inclinometer

摘要

At present, many common diseases including seepage, crack, segment staggering and longitudinal settlement, appear in the underground structure of urban track traffic. As one of main factors resulting in other diseases, longitudinal settlement can put great adverse influence on longitudinal performance of shield tunnel. So it is key to monitor longitudinal settlement accurately and timely. However, there are many shortcomings for the existed monitoring methods around the world. This paper presents a kind of real time monitoring method for longitudinal settlement of shield tunnel using Wireless Sensor Network (WSN) and Micro-Electro-Mechanic System (MEMS). Feasibility of the method is verified through MATLAB programming simulation, and the related technical parameters are determined based on present monitoring requirement.
