Abstract Research purposes: For construction of the new － type system bridge，the analysis and research should be done on the structural system pattern before the construction and the construction plan should be optimized according to the characteristics of the bridge construction． Based on the cable － stayed and self － anchored suspension of the Hanzhong Second Ring Road，the analysis and study were done on the structure features of the new composite structure and the optimization process．

Research conclusions: By research and optimization of the construction plan， the requirements of the construction safety，rationality and operability were met to make the construction going ahead smoothly and safely． For construction of new －type bridge structure，it was necessary to analyze the characteristics of the bridge structure and optimize the construction plan before construction． The characteristics of the bridge structure could be better understood by doing research on the optimization of the construction plan before construction． In this way，the construction could be finished safely and reliably．
