摘要
隧道工程衬砌结构由于长期处于复杂地层中,衬砌结构混凝土除了受到周围土质对其挤压作用外,还受到非荷载因素的影响,从而导致衬砌内表面出现类型各异的裂缝。文章介绍了隧道衬砌结构在非荷载作用下产生裂缝的原因,以及适用于裂缝修复的技术方法。
As experienced the adverse underground circumstances,in addition to the extruction from surrounding ground,the tunnel concrete lining also undergo the function from other factors,which lead to happen various cracks in the lining surface.The paper introduces the cause for appearance of cracks in tunnel lining under nonloaded function,and the convinient maintenance method.
