1.前言目前,国内外对机械荷载引起的开裂问题研究得较为透彻。而对温度荷载引起得有关裂缝的研究尚不充分。我们应对此加以重视,防止危害结构的裂缝产生。另外对于大体积混凝土内温度应力与裂缝控制也多集中在水利工程中的大坝、高层建筑的深基础底板。而对于桥梁中大体积混凝土的裂缝的研究并未得到足够的重视。本文将对此进行分析,探讨裂缝出现的原因及控制措施。
1. Introduction At present, the domestic and international research on cracking caused by mechanical load is more thorough. However, the studies on the cracks caused by temperature load are not enough. We should attach importance to this and prevent any cracks that endanger the structure. In addition for mass concrete temperature stress and crack control are also more concentrated in the dam, high-rise buildings in the deep foundation. However, the research on cracks in mass concrete in bridges has not been given enough attention. This article will analyze this to explore the causes of cracks and control measures.
