The foundation pit of Fuqing road station is the first one to be excavated in Ningbo urban rail transit project. To ensure the safety of the foundation pit, a detailed monitoring scheme is established according to the engineering geological condition and design scheme of foundation pit. Due to Ningbo city is located in the classical soft clay area, there may occur pre-warning and dangerous condition during the excavation. Therefore, reinforcement of structure and soil is executed from the aspects of designing, construction, supervision and monitoring. At last, the deformation of foundation pit is controlled and the construction safety is ascertained. Furthermore, the information construction is adopted during the excavation and many data are obtained during the process of monitoring, the displacement of diaphragm wall, ground settlement and axial force of the support are analyzed. In addition, the control measures are presented and can provide reference to the future construction of the other stations.
