The life cycle design in wharf project is very important, and it is one of the basic work for the theoretical research on the life cycle design to monitor the safety state in operation of existed works. In a crude oil terminal project of Dalian, according to the structure stress distribution, we laid the fiber bragg grating (FBG) monitoring system at important positions to observe timely the structural strain in the construction process of the main structure of concrete. It is of great significance for the validation and optimization of current design theory, building of the life cycle safety design theory, and establishment of the early warning system for the wharf structure.
