以某山岭隧道为实例，对结构产生的裂缝进行了调查和检测，就裂缝产生的主要原因及裂缝对隧道结构的影响程度进行了分析。按照无水裂缝和有水裂缝两种不同情况，分别就治理工艺和施工方法进行阐述。最后对防止隧道产生裂缝的措施作了简要说明。

Taking a mountain tunnel as example, the article makes investigations on and measurement of the cracks of the tunnel linings and makes analysis on the causes for the cracks and on the impact degree of the cracks on the tunnel structures.
