The application of the diaphragm pressure sensor in the monitoring of the construction of shield tunnel

In this paper,analysed the principle of strain film,the diaphragm pressure sensor technology is used to monitor the segment of shield tunnel during its construction.Compared with other traditional monitoring technologies,the diaphragm pressure sensor can achieve regional monitoring and has the advantage of lower prices.It can improve the comprehensiveness and reliability of monitoring.And it is shown that the diaphragm pressure sensor technology has good effect on monitoring of the shield tunnel.
