摘要
调研公路隧道检测现状,归纳总结发现对隧道的裂缝描述各个检测单位和相应人员均不一致,导致检测数据的运用存在很大的问题,尤其是裂缝发展趋势无法判定。基于隧道衬砌在JTGH 12-2015《公路隧道养护技术规范》中的比重,统一隧道裂缝描述方式:将隧道衬砌展布为平面形式,建立坐标系,简化隧道裂缝描述。通过裂缝数字化模型描述,可将裂缝描述定性化,通过连续性发现变化趋势,大数据的积累后可多方进行应用。
Investigate the current status of highway tunnel inspections and conclude that the crack descriptions of the tunnels are inconsistent with the description of the cracks by the various inspection units and the corresponding personnel,resulting in great problems in the use of inspection data,especially the crack development trend cannot be determined.Based on the proportion of the tunnel lining in“Technical specification for highway tunnel maintenance”,the tunnel crack description method is unified:the tunnel lining is spread into a planar form,a coordinate system is established,and the tunnel crack description is simplified.Through the description of the crack digital model,the crack description can be qualitative,and the change trend can be found through continuity,after the accumulation of big data,it can be applied in many ways.
