大体积圆形承台施工技术分析

Analysis of Construction Technology for Large Volume Circular Bearing Platform

文中以永定河大桥为例,阐述大体积圆形承台浇筑流程中质量管理要点和大体积砼温度控制方案。该方案能达到混凝土强度设计和标准要求,有效防止混凝土开裂的形成与扩展。

Taking Yongding River Bridge as an example,this paper introduces the quality control points and temperature control methods of mass concrete in the construction process of mass circular cap.Promote concrete strength to meet the requirements of design and specification while effectively prevent the generation and development of concrete cracks.
