高速公路各板梁横向之间通过现浇的混凝土铰缝和焊接钢板联结,借此将各板梁横向连成整体,使作用于行车道板上的局部荷载分配给各板梁共同承受,这样就能显著地减小单根板梁受力,达到经济目的。板式桥梁中铰缝构造的病害造成的原因很多,文章在分析的基础上,提出了处治的有效措施。
Through the concrete pouring concrete joints and welded steel plates, the horizontal direction of each girder of the expressway is connected with each other so as to connect the girders transversely and to make the partial loads acting on the traffic lane plates to be shared by the girders. Can significantly reduce the stress of a single beam, to achieve economic goals. There are many reasons for the disease of hinge joints in the plate bridge. Based on the analysis, the article puts forward the effective measures of treatment.
