重载卡车下三跨连续梁桥的设计

Design of three span continuous beam bridge under heavy loading trucks

公路桥梁设计时采用的车辆荷载对应的质量一般是55 t,因此,对桥梁结构物的承载能力的设计要求较高,各类规范对此类桥梁的设计亦没有相关规定。针对实际设计案例,设计并计算大吨位卡车下的桥梁结构。

The weight of vehicle load in the highway bridge design is generally 55 tons. The design requirement is high on bearing capacity of bridge structure. All kinds of specifications for this kind of bridge design has no relevant provisions. This article designs and calculates a bridge structure with a large tonnage truck aiming at the practical design.
