Abstract：Research purposes: In order to improve the comfort when driving through the bridge，some client required that the continuous hollow slab beam erected as simple-supported beam in advance should be adopted in the design. So the author made some analysis of this structure.
Research methods: Using the structrue calculation program，this paper gets the stress characteristic of continuous hollow slab beam erected as simple-supported beam in advance. At the same time，this paper compared the continuous hollow slab beam erected as simple-supported beam in advance with another similar beam structures and the economic indicators are also analyzed.
Research results: The difficulties and main essentials of the calculation of continuous hollow slab beam erected as simple- supported beam in advance are resolved and the anticipated goal is achieved.
Research conclusions: The leveling course of bridge deck should be regarded as stress unit. The calculation of cast-in-place section of the beam above the pillar should be carried on according to the reinforced concrete component. Regarding prefabricated hollow slab beam，the calculation should be carried on according to pre-stressed concrete component of sort A or sort B. The continuous hollow slab beam erected as simple-supported beam in advance has competitive advantage in the medium span continuous beam structure and the structure is safe and economical.
