大型桥梁等构筑物不断的增多,大型混凝土连续的浇筑和硬化过程产生的大量的水化热不能及时排出时将导致混凝土开裂。另外设计不合理,施工不规范,施工工艺存在质量问题等,都有可能使混凝土产生裂缝。介绍了桥梁混凝土不同时期裂缝产生的主要原因和产生裂缝种类及几种控制措施。希望为今后桥梁混凝土开裂防治提供参考。
Large bridges and other structures continue to increase, large concrete continuous pouring and hardening of the large amount of heat generated by hydration can not be discharged in time will lead to concrete cracking. Another unreasonable design, construction is not standardized, there are quality problems in the construction process, are likely to make concrete cracks. This paper introduces the main causes of cracks in different periods of bridge concrete and the types of cracks and some control measures. Hope for the future prevention and treatment of bridge concrete cracking provide a reference.
