Zusammenfassung:	The invention discloses a tunnel service life detection and evaluation method. The method comprises the following steps: S1, collecting tunnel lining fundamental frequency vibration frequency information; s2, calculating the remaining service life of a tunnel lining at a certain point and a certain moment; and S3, calculating the remaining service life of a certain mold of the tunnel lining at a certain moment. The method can realize the detection and evaluation of the residual service life of the tunnel lining, has the characteristics of convenient collection of the residual service life parameters of the tunnel lining and simple evaluation method and process of the lining service life, and solves the problems that the evaluation of the residual service life of the tunnel lining needs to collect various parameters, the calculation process is complex and the evaluation is difficult to implement. 本发明公开了一种隧道服役寿命的检测和评价方法，包括以下步骤：S1：隧道衬砌基频振动频率信息采集；S2：隧道衬砌某点某时刻剩余使用寿命计算；S3：隧道衬砌某模某时刻剩余使用寿命计算。可实现隧道衬砌剩余服役寿命的检测和评价，具有隧道衬
