Abstract：Research purposes: According to the terrain geological conditions and the status of the existing structures， this paper discusses the alternative option of the shed hole structure in order to optimize the structural style of shed hole.
Research methods: By using structural analysis to find the control factors in the design of the shed hole structure and aiming at these control factors to compare the several different shed hole structure designments，the better designment can be confirmed.
Research results: Through systemic analysis，the style that a composite structure which is composed of independent reinforced concrete framework and simply supported beam is adopted. It has been constructed by June 2002 and it has been working well.
Research conclusions: The Labaxi shed hole is a statically indeterminate structure，whose structure design is controlled by shrinkage creep of the concrete and the temperature stress as the temperature decreasing. The composite structure can not only guarantee the general stability of the shed hole but also reduce the temperature stress.
