摘　　要：通过对已有常用D型施工便梁进行归纳、总结,拟定了跨度为40m的超长D型施工便梁的结构尺寸,并通过MIDAS Civil软件进行整体建模,模拟梁体受力状态,检算梁体在列车活载作用下的强度和变形,为D40型施工便梁的制造提供理论依据。This paper summarizes the existing and common used D-type construction auxiliary beam, and proposes the structure size of super long span D-type construction auxiliary beam with a span of 40 m, and through the overall modeling by MIDAS Civil software, the strength and deformation of beam body under the action of live load is simulated, which provides a theoretical basis for the manufacture of D40 type construction auxiliary beam.
