Temperature field analysis is the key of the study on the rules of freezing defects of tunnels in cold areas. A client software of the temperature remotemonitoring system based on Android program is developed on basis of GPRS temperature remotemonitoring, in order to realize realtime remote monitoring of the temperature at any position and at any time. The software can achieve such functions as user management, system operation checking, historic curve checking, realtime monitoring data checking and report table sending. The software developed has been applied in the monitoring of the temperature field of tunnels in seasonallyfrozen soils in Northeast China, which shows that, due to the application of the software, the working intensity of the monitoring labors is reduced, the monitoring cost is minimized and the monitoring level is improved.
