摘要
针对大跨度钢结构拱脚安装中两个角度倾斜,定位难的问题,介绍了根据整体测量网进行拱脚定位的过程,以确保拱脚的安装精度。从设计、混凝土配合比及材料选择、混凝土养护、温度监测以及防意外措施等方面介绍混凝土结构裂缝控制措施,从而保证大体积混凝土的施工质量。
According to the problems that inclined two angles and arch foot location of large-span steel structure,the location processes of arch foot according to monolithic measurement network is introduced to insure the installation accuracy.Some measures are introduced to control concrete cracks and insure the construction quality of mass concrete.The measures include design,concrete mixture ratio and selection of materials,concretecuring,temperature monitoring and measures of preventing accident.
