摘要
提出了梁桥（以少筋微弯板梁桥为例）大边梁加固的新方法，即仅加固梁桥的边梁，使边梁截面尺寸增大，刚度增加。该法便于施工，可有效改善荷载分布，降低内梁所分配到的活载，从而提高全桥承载力。发展了斜梁桥的“广义弹性支承连续梁”理论，使大边梁桥梁的荷载横向分布计算简单明了，并以此分析正桥的荷载分布，得到了几点结论。
A new method is presented for strengthening multi beam bridge with big external girders. The stiffness and cross section of external girder can be increased with this method. This method is convenient to engage in construction. This method can improves load distribution effectively, reduces live load of internal beam and increases bridge carrying capacity. The theory of General Elastic Supported Continuous Beam in skew girder bridge is developed to analyze transverse load distribution of right bridge. Server conclusions are obtained.
