现代战争军事装备趋向重型化,需要有与之相适应的运输技术装备作为重装备的运输保障手段。出于隐蔽和快速机动的需要,一些军事重装备要求通过承载能力不够的低等级或破损公路桥梁,因而需要对这样的桥梁提供一整套加固办法。 石家庄铁道学院国防交通研究所,多年来通过对军事重装备和重型工业设备公路运输的实践,在“桥上桥”技术加固桥梁的基础
Modern warfare military equipment tends to be heavy-handed, requiring appropriate transport technology and equipment to be used as transport security means for heavy equipment. For reasons of covertness and rapid maneuvering, some military heavy equipment requires the passing of a low grade or damaged highway bridge that does not have sufficient carrying capacity and therefore requires a complete reinforcement of such a bridge. Shijiazhuang Railway Institute of National Defense Traffic Research Institute, over the years through the military heavy equipment and heavy industrial equipment road transport practices in the “bridge on the bridge” technology to strengthen the bridge foundation
