The structure system, not the single component is studied for the first time. The model of system reliability of aqueduct system that based on main failure modes and comprehensive correlation coefficient method is established, in which the system reliability of pile beam multi-lateral wall of Minghe aqueduct is analyzed. It is showed that the worst failure modes of structure system and its impact on reliability and durability of entire system can be revealed simply and accurately. It also offers a controlled basis for the optimal design and plan of operation and management. Compared with PNET, it embraces the same accuracy. The method can avoid the influence caused by PNET for subjectively determining limit correlative coefficient. It is proved to be a practicable method for analyzing structure system reliability for the complex project.
