longitudinal girder

基本解释

Compared with ordinary continuous longitudinal girder, this type of wharf has an obvious decrease in internal forces.
通过内力计算并与传统梁板式码头的比较，结果表明该码头结构形式跨中内力明显减小。
It is proved when the longitudinal girder is far sway from the grounding area, it fails to play its energy absorption ability and fails to show its grounding-resistance effect.
当纵桁远离搁浅区域时，它的吸能能力无法发挥，抗搁浅作用明显削弱。
Moreover, it puts forward suggestions to modification of the calculation span of longitudinal girder stipulated in the Design and Construction Code of High-piled Wharf (JTJ291-98).
对《高桩码头设计与施工规范》（JTJ291-98）中的纵梁计算跨度提出了修改建议。
