—This paper presents an experimental study of a prestressed lightweight concrete platform mod-el with a tank and five steel columns.This platform can be used not only for extraction but also for storageof oil and is suitable for the Bohai Sea and other shallow seas of China.The platform is subjected to tem-perature.load.or both.The corresponding temperature distribution.strains.cracks.and vulnerable partsof the platform are analyzed respectively.By use of the finite element method and empirical formulas.thetemperature field of the model is analyzed.The results agree with the experimental results.thereby veri-fying the reliability of these two calculating methods.The paper provides an experimental basis for the de-sign of the bearing capacity and normal service state of prestressed concrete platforms.
