摘　　要：为提高高层建筑的安全性能,施工单位经常使用大体积、高性能混凝土。但大体积混凝土对施工技术也提出了更加严格的要求,如由于水化热特性的影响,须做好后期养护,以防止混凝土出现裂缝等质量问题。以金州新区医疗中心综合楼工程为例,首先概述了该工程施工中的重难点技术,随后分别从前期施工准备,中期混凝土浇筑施工以及后期大体积混凝土养护等方面,就如何提高底板大体积高性能混凝土的整体质量展开了分析。In order to improve the safety performance of high-rise buildings,construction units often use large-volume,highperformance concrete. However,mass concrete also puts more stringent requirements on the construction technology. For example,due to the influence of hydration heat characteristics,it is necessary to carry out post-maintenance maintenance to prevent concrete from cracking and other quality problems. Taking the comprehensive building project of Jinzhou New District Medical Center as an example,the paper first summarizes the heavy and difficult technology in the construction of the project,and then how to improve the large volume of the floor from the aspects of pre-construction preparation,medium-term concrete pouring construction and late bulk concrete curing.The overall quality of high performance concrete was analyzed.
