摘要
大体积水泥混凝土施工中,由于施工环境以及自身凝结硬化过程中,混凝土内外温差较大等原因,极易产生裂缝等病害。文章结合内蒙古乌海黄河特大桥中大体积水泥混凝土施工实践,分析总结了乌海黄河特大桥中大体积水泥混凝土施工工艺及病害处理措施,与同行共享。
As the temperature difference between inside and outside of concrete is large under the construction environment and self condensation hardening process, the large volume concrete easy to produce disease such as fracture during construction. Combining with construction practice of the Yellow River extra - large bridge in Wuhai, Inner Mongolia, this paper analyzed and summarized the large volume concrete construction process and disease treatment measures, to share with colleagues.
