本文提出了确定补偿收缩混凝土结构预压应力的一个新方法:即从理论上求出补偿收缩混凝土结构的约束系数,再通过钢筋模拟约束试验测定预压应力,这样既把补偿收缩混凝土的预压应力试验与实验结构联系起来,又避免了纯理论计算带来的近似性。 This paper proposes a new method for determining the precompressive stress of a compensated shrinkage concrete structure: the constraint coefficient of the compensated shrinkage concrete structure is obtained theoretically, and the precompressive stress is determined by the reinforcement simulation test, so that the precompression of the shrinkage-reducing concrete is not only compensated. The stress test is linked to the experimental structure, which avoids the similarity brought about by pure theoretical calculations.
