| Abstract: | The paper introduces the optimized construction of 40m precast prestressed reinforced concrete box beam of Jialuhe Bridge of south-west highway of zhengzhou city. Preast pieces are connected to be continuous beam by cast-in-place middle cross beam and wet joint to achieve the first simple supporting and late continuing. So it also compares simply supported beam with continuous beam bridge. |

| Keywords: | precast beam first simple supporting and late continuing optimized construction |
