THE TEMPERATURE STRESS ANALYSIS OF THE PRESTRESSED CONCRETE HOLLOW BEAM

摘要

摘要: 以南京新机场高速公路施工预制场预制的预应力空心板梁由于温度应力产生的裂缝为例，进行了温度应力的分析和计算，并提出了裂缝的预防和弥补的措施．

Abstract: In this paper, the temperature stress isanalyzed and calculated. An example is taken fromthe crackings appeared at the prestressed concretehollow beam of precast girders in the Nanjing newairport freeway. The precaution and the rehabilitation of the crackings airs proposed.
