地铁车站侧墙裂缝机理分析和控制

Analysis and Comsrol of Side Wall Crevice in Subway Station

分析了地铁车站侧墙裂缝产生的机理和原因。通过降低水泥的水化热,降低混凝土浇注温度及外界气温,降低混凝土的干缩变形,配置适量的钢筋等措施,可控制裂缝的发生和发展。

This paper discusses the mechanism of temperature crevice emergeds on side wall and the main factors which affect the temperature crevice in subway station, holds that the calculation and the control of the temperature in concrete pouring, the proper disribution of reinforcing bars will effectivily control crevice in subway station side walls.
