摘要
以国内外不同的隧道结构状态评价方法为基础,从裂缝的宽度、长度,衬砌的剥落,材料的劣化及渗漏水等方面进行讨论,并以北京地铁复八线为研究对象,依据裂缝宽度、长度及衬砌掉块厚度、范围等将裂缝病害分为5级,衬砌掉块病害分为4级,研究地铁矿山法区间隧道衬砌病害分级标准及相应的补强对策。
According to different evaluation methods of tunnel structure state in China and overseas,the crack width,crack length,lining spalling,material degradation and leakage water were discussed.By taking the ‘ Double-8 line＇ in Beijing subway as the research background,the crack damage is classified into five degrees,and the lining chip off-falling damage is classified into four degrees based upon crack width,crack length,thickness of lining chip off-falling and range of lining chip off-falling.The damage classification criterion and reinforcement strategies of mine construction subway are studied.
