According to the above analysis, the system can use high-precision angular displacement sensors installed on bridge piers to transmit the collected angle signals to the computer through signal adjustment devices. After data processing, the horizontal displacement values of each pier of the bridge can be given. Furthermore, during the pushing process, the force measuring device also transmits the measured oil pressure signal to the computer, which is converted into the pushing force. The computer monitors the displacement and thrust of the pier top in real-time and displays these data on the screen. Figure 8 shows the relationship between angular displacement and linear displacement and the measurement principle diagram
