摘要:
根据钢筋锈蚀后砼的开裂状态,以及现有胀裂锈蚀量的计算模型特点,考虑砼相对保护层厚度的影响,提出一种更符合工程实际情况的砼胀裂时钢筋锈蚀量的计算模型 .经实例验证,该计算模型可行、有效,计算结果与实际情况相符合 .
Abstract:
For computing corrosion rate of reinforcing bar following spalling of concrete cover, the authors present a model even more satisfying actual situation of engineering. The computation model is based on cracking state of concrete after corrosion of reinforcing bar; it directs against the characteristics of existing model for computing corrosion rate after spalling of concrete cover; and it takes the influence of relative thickness of concrete cover into consideration. The computation model is confirmed by living examples to be feasible and effective; its reckoning tallies with actual situation.
