The invention provides a concealed elastic-plastic settlement structure for a vehicle driving pavement of an underground tunnel, which relates to the field of settlement structures for pavement of underground tunnels and comprises a reinforced concrete bottom plate A and a reinforced concrete bottom plate B, a settlement joint is reserved between the reinforced concrete bottom plate A and the reinforced concrete bottom plate B, and a concrete cushion layer is poured on the upper portion of each of the reinforced concrete bottom plate A and the reinforced concrete bottom plate B; through cooperation of the elastic-plastic body filling groove, the TST elastic-plastic body, the hot-melt polyester fiber geotechnical cloth, the medium-grain asphalt concrete layer, the asphalt mastic macadam mixture layer and the connecting steel plate, after the main body structure is settled, the TST elastic-plastic body bridge seamless expansion principle is combined, so that reflection cracks are not prone to being formed on the asphalt surface, and the service life of the main body structure is prolonged. Convenience is brought to underground tunnel construction quality control; the problems that a traditional settlement structure of a vehicle driving road surface of an underground tunnel is prone to forming reflection cracks on the asphalt surface after settlement, and troubles are brought to underground tunnel construction quality control are solved.
本发明提供一种地下隧道车行路面暗埋式弹塑沉降结构，涉及地下隧道路面沉降结构领域，包括：钢筋混凝土底板A和钢筋混凝土底板B；所述钢筋混凝土底板A与钢筋混凝土底板B之间预留有沉降缝，且钢筋混凝土底板A和钢筋混凝土底板B上部均浇筑有一个混凝土垫层；本发明通过弹塑体填充凹槽、TST弹塑体、热熔型聚酯纤维土工布、中粒式沥青混凝土层、沥青玛蹄脂碎石混合料层和连接钢板的配合，使得主体结构沉降后，结合TST弹塑体桥梁无缝伸缩原理，从而不易在沥青表面形成反射裂缝，为地下隧道施工质量控制带来便捷；解决了传统地下隧道车行路面的沉降结构，在沉降后，容易在沥青表面形成反射裂缝，为地下隧道施工质量控制带来麻烦的问题。
