摘　　要：结合某地一个具体案例,利用先进的隧道状态激光全息成像扫描技术和岩土测试技术对区间隧道进行综合全面的健康检测。根据隧道状态激光全息成像扫描采集的数据信息以及隧道混凝土强度检测和钻孔取芯的结果,对隧道裂缝、渗漏水、椭圆度、错台、变形、收敛、混凝土强度情况以及道床脱空情况等进行全面分析和评价。Combined with a specific case in an area, comprehensive health detection of tunnel is carried out by using advanced laser holographic imaging scanning technology and geotechnical testing technology. According to the data information collected by laser holographic imaging scanning of tunnel state and the results of tunnel concrete strength detection and core drilling, tunnel cracks, leakage, ellipticity, staggered platform, deformation, convergence, concrete strength and ballast void are comprehensively analyzed and evaluated.
