混凝土桥墩裂缝成因分析

Analysis on Crack Causes of Concrete Bridge Pier

摘要:

大体积混凝土结构在施工过程中的后期易因水化热的温升产生裂缝，而老混凝土的约束作用又对裂缝的产生有一定的影响。现利用有限元分析软件对一混凝土桥墩的裂缝的成因及其影响因素进行分析，从而得出老混凝土的约束作用会加剧裂缝的产生并改变裂缝的形成位置的结论。

Abstract:

The temperature rise of hydration heat tends to cause the cracks in the mass concrete structures in the later period of construction, and the restraining action of old concrete will also have certain influence on the cracks. The finite element analysis software is used to analyze the crack causes of a concrete pier and its influence factors so as to obtain the conclusion that the restraining action of old concrete will exacerbate the cracks and change the forming position of crack.
