箱形板梁制造简单,整体性强,养护维修方便,具有较大的抗扭刚度和节省钢材的特点,因此是桥梁结构发展方向之一。箱形板梁这一种新型桥梁结构,国外发展甚快,我国于1966年至1968年首次设计、建造了一座32米整体式箱形钢板梁于潼河桥,经过十多年的运营考验,结构受力状况良好。随着科学技术的发展及对高腹板的试验研究,于1979年由专业设计院标准处设
Box girder manufacturing simple, strong integrity, maintenance and repair convenience, with greater torsional stiffness and save the characteristics of steel, it is one of the development direction of the bridge structure. Box girder is a new kind of bridge structure developed rapidly abroad. In 1966 to 1968, China first designed and built a 32-meter monolithic box girder at Tong River Bridge. After more than a decade of operational tests, The structure is in good condition. With the development of science and technology and the experimental study of high web, in 1979 by the professional design institute standard office
