摘　　要：以实际工程为例,针对沉箱顶到码头面高差较大工况下的门机后轨道梁进行优化设计,可有效节约工程量,降低工程造价,且满足轨道受力要求。Based on practical project, for the condition that the distance of top caisson from wharf surface is much farther than the normal quay, the design optimization of gantry crane＇s rear rail girder can reduce the quantities of concrete and sav ing the construction cost, and meet the requirements for the stress of railway.

关 键 词：门机后轨道梁 沉箱后壁 优化设计
