摘要
定义了何为大体积混凝土,研究关于大体积混凝土在施工中易产生的技术难题以及采取如何防治的措施。介绍新井冈山大桥塔座施工,主要对塔座大体积混凝土施工中容易出现裂缝的原因进行分析,从而制定一系列的改善措施,提高大体积混凝土抗裂、抗侵蚀性,提高混凝土结构的耐久性。
In the course of continuous development and practice,endless problems turn out. The definition of mass concrete is determined,and the technical difficulties that may occur in the construction of mass concrete and how to take measures to prevent and treat it are studied. The construction of the pylon seat of the new Jinggang Mountain Bridge is introduced. The cause of the cracks in the mass concrete construction of the pylon seat is analyzed,and some improvement measures are formulated to improve the crack resistance and corrosion resistance of the mass concrete and to improve the durability of the concrete structure.
