| 7. | Based on these theoretical studies , the temperature stress and shrinkage stress of plain concrete slab and reinforced concrete slab are calculated using finite element analysis software adina , and the differences between them are also made 在此理论研究的基础上,通过有限元分析软件adina来计算素混凝土平板构件和配筋混凝土楼板的温度应力和干缩应力,比较其抗裂性能的区别。 |
| 8. | Then according to temperature gradient and humidity gradient , which are the essential factors inducing concrete cracks , distribution of thermal and moisture within young concrete and numerical methods to calculate temperature stress and shrinkage stress are systematically analyzed 然后针对引起混凝土开裂的本质因素即混凝土内部的温湿度梯度,系统地分析了混凝土温湿度场的变化规律及温度应力和干缩应力的数值计算方法。 |
| 9. | The change of moisture distribution is concentrated on the surface layer concrete , which is very thin . however , the change inside the concrete is very slight . this unbalanced development of moisture distribution causes large shrinkage stress in the layer concrete and then leads to crack 混凝土湿度变化主要集中于较薄的表层混凝土内,内部湿度场变化极微,这种湿度发展变化的不均衡使得表层混凝土内产生较大的收缩应力,将直接导致裂缝的产生。 |
| 10. | If the surface is covered or watered after casting of concrete , the influence resulted from change of environmental temperature and relative humidity on concrete will decrease to some extent . then the shrinkage stress will also decrease and the probability of cracking will be reduced as well 混凝土浇注完后对表面进行覆盖或浇水养护,可以很大程度上地减少外界温湿度变化对混凝土内部的影响,减小了混凝土的收缩应力,从而降低混凝土开裂的可能性。 |
