In order to study the mechanical behavior of U-rib internal welding of orthotropic plate, the three-dimensional thermal coupling model of U-rib of orthotropic plate was established by using ABAQUS finite element software, and the structural stress distribution law of welded joints in three groups of welded joints was analyzed in four kinds of loading conditions by taking into consideration of the presence of weld toe on the inner side, different sizes of weld toe on the inner side, and different welding melt depths. The results show that the structural stress distribution law of single-sided welding and double-sided welding is the same, the structural stress of the outer weld toe of the bridge deck plate and the outer weld toe of the U-rib is more than 80 MPa under unfavorable working conditions, and the cracking chance is the greatest, the change of melting depth has the greatest influence on the structural stress of the outer weld, and the setting of inner welding can effectively improve the structural stress and improve the welding quality.
