现结合某工程施工实例，将混凝土内外温差控制在25以内能有效防止裂缝出现，从而确保了混凝土的施工质量，达到了大体积混凝土防射线的效果。 |
| 7. | Because of the lack of understanding of its characteristic , in recent years the problem of masonry ' s crack have badly influenced masonry ' s function . if we have enough knowledge about the basic mechanical behavior of new material of block , and study the cause of crack , the emergence of crack can be avoided
但由于对其特性把握不足，近年来砌体建筑墙体裂缝问题频出，已影响到使用功能，只有充分的了解新型墙体材料的力学性能，研究裂缝产生的机理，才能更好的防止裂缝的产生。 |
| 8. | The heat transfer and the restriction circumstance are simulated . the temper ature - time curve and the stress - time curve are obtained . because the later joint - filled slots are restrained strongly , in which the thermal stress is great , especially in the corner , in spite of a little temperature rise , some measures should be taken to prevent them from producing cracks
利用有限元前处理软件vizicad建立了“ t ”形后浇带模型，模拟了后浇带的“热环境”和“约束环境” ，计算得到了后浇带的应力和温度发展曲线，发现虽然后浇带的温升不大，但受到的约束较大，因此产生较大的温度应力，特别是在其拐角处，应采取措施防止裂缝的出现。 |
