| 摘 要： | 通过现场实测及采用有限元理论评估分析后，认为目前打浦路隧道圆形段车道板结构不仅能满足原设计的承载要求，而且也能符合汽－20级的承载标准，但由于挂－100级通行时，车道板混凝土的拉应力已超过其允许强度，故建议将挂－100级作为特殊车辆，由管理部门审批后准许通行。

| Abstract: | After site testing and estimative analyzing with finite element theory,the structure of the traffic lane slab in the circular section of da-pu road tunnel not only meets the bearing requirement of the original design,but also conforms to the bearing standard of Automobile-20 at present.Because the tensile stress in slab concrete is more than its working strength when Trailer-100 pass the lane slab,it is suggested that Trailer-100 are regared as special vehicles and they have to be ratified to pass da-pu road.tunnel by a management department. |
