Measurement system of tunnel lining behavior during an earthquake

摘要

PROBLEM TO BE SOLVED: To provide a measurement system for a tunnel lining behavior during an earthquake which obtains the lining behavior of a tunnel in real time during the earthquake.;SOLUTION: In the measurement system for the tunnel lining behavior during the earthquake, a sensor 2 having a strain gauge 4 and a wireless transmitter 10 connected to the sensor 2 are disposed on a lining surface 1 of the tunnel 14. The measurement system is provided with: a wireless receiver 20 for receiving information on a deformation of the lining surface 1 of the tunnel 14 from the wireless transmitter 10 outside the tunnel 14; and a tunnel covering plate deformation information analyzer 30 for analyzing the information on the deformation of the lining surface 1 of the tunnel 14 from the wireless receiver 20.;COPYRIGHT: (C)2010,JPO&INPIT
