在实地调查山西省某在建高速公路黄土隧道二次衬砌裂缝病害特征的基础上,通过数值模拟方式并从黄土结构性角度出发对该黄土隧道二次衬砌裂缝成因进行了分析,相关分析结果对提高黄土隧道二次衬砌开裂机理的认识及处治措施的选择具有参考价值和实际意义。
Based on the field survey of the characteristics of the secondary lining cracks in a loess tunnel under construction in Shanxi Province, the cause of the secondary lining cracks in the loess tunnel was analyzed by means of numerical simulation and from the perspective of loess structure. The correlation analysis showed that It is of reference value and practical significance to improve the understanding of cracking mechanism of secondary lining in loess tunnel and the choice of treatment measures.
