METHOD FOR OBSERVING SETTLEMENT AND CONVERGENCE OF TUNNEL

摘要

A method for observing settlement and convergence of a tunnel, which relates to the field of methods for observing settlement and convergence of tunnels. The method for observing settlement and convergence of a tunnel comprises: 1) select a plurality of observation points on the vault and two sides of the vault of the tunnel, carry punching at the selected observation points, finally, fix hooks at the observation points by means of through holes and expansion screws; 2) fix, by means of screws, a plurality of signal transmitters (1) capable of automatically transmitting microwave signals on the hooks; 3) respectively select two reception points on walls on two sides of the tunnel close to the bottom, and fix receivers (2) for receiving signals at the reception points; and 4) a survey worker copies internal memory data of the receivers every day by means of a USB flash disk, brings the USB flash disk to a room and imports the data to a computer, and settlement and convergence results can be obtained after software processing. All-day and all-weather work can be realized, operation of workers in the observation process is not required, the signal transmitters and the receivers are hung on the walls of the tunnel and are not influenced by construction, position errors caused by each time of erection when a total station is used for observation are avoided, and the observation precision is improved.
