Abstract：Slurry shield with outer diameter of 11.58 m was used in Shanghai West Xianxia road tunnel which was undercrossing the taxiway of Hongqiao airport. Through the risk analysis of shield crossing construction，the corresponding control measures were given. Before advancing of the shield machine，the control rules of construction parameters of tunnel shield were studied through field driving test，which provided the guidance for construction parameters settings during shield advancing；finally，the settlement value met the control standard requirement of airport taxiway. In order to solve the limitation in terms of monitoring space and frequency on ground settlement in flight forbidden zone，the horizontal inclinometer monitoring method is applied by using trenchless technology，through which monitors could know the accurate disturbance of soil above the shield in time. The monitoring data show that horizontal inclinometer monitoring by trenchless method can indicate the deformation rules of soil layers when the shield is undercrossing the airport without flights stopping. This kind of monitoring method avoids the disturbance to the airport operation，which is significant to the similar projects.
