Abstract：Research purposes: The settlement of the light rail bridge around the Xunlimen Station of Line 2 of Wuhan metro was considered to be stabilized after the analyzing the monitored data and optimizing the construction plan．However．it was necessary to further study whether the absolute settlement and differential settlement of the bridge pier could meet the operational requirement of light rail or not to make sure the coordination of newly—-built underground structure with the operation of the ground structure for meeting the service requirements for them．
Research conclusions:From the calculation of the numerical values of the light rail bridge pier，analysis of the monitored data settlement and comparison with the corresponding codes it is concluded the existing settlement of the light rail bridge call meet the service requirement of light rail．
