摘要：增大截面法加固的钢筋混凝土梁属于新旧材料二次组合梁，能否成为一个整体，关键取决于结合面能否充分传递剪力。为了确保新旧混凝土协同工作，剪力可靠传递，达到良好的加固效果，本文通过对三种不同结合面处理加固梁的力学性能进行了研究。结合面粘贴钢丝网的处理方式，可以改善梁的受力性能，提高梁的承载力，加固效果好。 Abstract: Reinforced concrete beams reinforced by section enlargement method are new composite beams of old and new materials, whether they can become a whole, it depends on the joint surface whether it can fully transfer shear. In order to ensure the old and the new concrete working together, transfering shear reliably, and reaching a good reinforcement effect, the mechanical properties of reinforced beams strengthened by three different bonding surfaces are studied. The method of bonding steel wire mesh on the surface, which can improve the beam performance and the bearing capacity of the beam and achieve a good reinforcement effect.
