摘　　要：为研究环境温度缓慢变化对玄武湖隧道90 m长无缝段结构变形的影响,对隧道环境温度变化及变形缝变形情况进行了现场监测,监测结果表明,结构温度变形与温差非线性相关,在温差不大时,变形缝宽度开展速度比较慢,超过10℃以后,变形缝宽度开展速度增大。In order to research on the slow changes of environment temperature＇ s influence on 90-meter seamless structural deformation in Xu- anwuhu tunnel, the paper inspects the temperature changes of the tunnel environment and its deformation joints. It is shown by the inspection results that the structural temperature deformation has something to do with the nonlinear temperature. As the temperature differences is not obvious, the development speed for the deformation seam will be slow, while the temperature is above 10 ℃, the speed will be quick.
