Abstract: The 7 sets of 30 t cable crane were taken to pour concrete for Baihetan hydropower dam. Double layer shift arrange was adopted, including 3 sets of cable crane on higher elevation with a span of 1 058 m, as well as 4 sets of cable crane on lower elevation with a span of 1 088 m. The cable cranes foundations located in the excavation slope. It was difficult to design, because of huge horizontal force, the complex terrain and geological conditions. According to topographic and geologic conditions, appropriate structure type was selected for every segment of the track foundation of cable cranes. Using bruteforce method, possible operating conditions were analyzed and the most unfavorable position of every cable crane, internal forces network diagrams and displacement envelope of the track foundation were obtained. Accordingly, the size of structure, reinforcement and complementary measures for structural stability were determined.
