Abstract：The single system across two environments testing method is presented for inspecting mechanical parameters of engineering structures on the field condition under low temperature. Two different environments are established by adding testing vehicle. Test can be carried out with a single test system, in which test instruments and computers are arranged in the vehicle environment of higher temperature, but the low-temperature sensors are fixed on the tested structures in low temperature environment directly. Testing data can be transmitted between the instruments and sensors by special signal wire. A trail of contrast experiments on displacement and strain indicates that the present method is rational and accurate. The results on a steel truss bridge show that the present testing method of single system across two environments can test mechanical behaviors of engineering structures on the field condition under low temperature effectively.
