KESSEM隧洞混凝土衬砌裂缝控制技术

Fissure control technology of the concrete lining of Kessem tunnel

裂缝是混凝土建筑物主要的病害之一,主要由砂石料的质量、混凝土干缩、混凝土拌和质量、水泥水化热、温度、钢筋锈蚀、地基变形、荷载应力等因素引起.通过采取各种控制技术措施,KESSEM引水隧洞洞室衬砌工程混凝土裂缝现象基本得到了控制,取得了良好的效果.

The fissure is one of the illness of concrete buildings, which is gotten rise to by the sand quality, the dry shrinkage of concrete, the mixing quality of concrete,the hydration heat of cement, temperature, the corrosion of steel bar, the subbase deformation and the load stress. Through adopting several technology measures,the concrete fissure of the lining of Kessem tunnel is controlled. The effect is good.
