Fuzzy grey multi-criteria decision making method is used to build the carbon fiber reinforced polymer for water conservancy engineering construction simulation analysis model of composite materials, mainly through the establishment of different sandwich relative density of carbon fiber reinforced polymer composite materials (CFRP) square honeycomb sandwich structure under the effect of underwater explosion shock wave load simulation model, analyses the structure of the deformation process, sandwich compression feature and structure of the failure and damage. Based on the empirical analysis results of the new material, the construction schedule of the water conservancy project is optimized. The results show that the maximum compression of the honeycomb sandwich of CFRP composites increases slowly and then rapidly with the increase of the initial pressure. The failure of CFRP composite sandwich structure presents different modes with the change of relative density and initial pressure, and its protection performance is better than that of equal-weight laminated structure. This research result can provide reference for optimizing the construction schedule of hydraulic engineering, especially for the construction optimization of new composite materials.
