黄土隧道仰拱裂纹产生原因分析及处理措施

摘要

以某黄土隧道仰拱出现裂纹为例, 通过沉降开裂观测数据, 分析了隧道仰拱裂纹产生的原因, 并提出相应的处理措施.%Taking the cracks in the inverted arch of a loess tunnel as an example, based on the observation data of subsidence cracking, the causes of tunnel invert cracking were analyzed, and the corresponding treatment measures were proposed.
