Bearings for the Girders:The longitudinal girders have to rest over the piers which bears the thrust of the load coming over them.In order that the girders ends should rest on proper seats,the same are provided with bearing blocks made of cement concrete,so that the load may be uniformly distributed over the structure on which they rest.Due to the expansion and contraction of the longitudinal girders during severe heat and cold,rollers are provided on the abutment ends to allow the movements without causing the girder to buckle.

梁（桥面）的支撑方式；纵向梁要放置桥墩上面,而桥墩要承受桥面上运行的车辆产生的纵向冲击力,梁的两头要准确地放置在由混凝土浇筑成的支撑块上面,以使得支撑物（桥墩）的受力均匀,由于爆冷或暴热会造成梁的纵向伸缩,为了避免造成梁弯曲（变形）,在梁的支撑点处要装滑动辊（也叫晃墩）
