摘　　要：提出了内削外补法加固梁的概念,并通过试验对内削外补加固梁在增大截面宽度和初始荷载因素影响下的力学性能进行研究。试验结果表明:内削外补法加固梁极限荷载受初始荷载等级的影响较大,但是该方法可有效提高梁的极限承载力和刚度,可为类似工程提供参考。The concept was presented to beams strengthened by the method of internal broaching and external patch,and an experimental program was carried out to study the behavior of beams strengthened by this method.Two main factors were considered in the test,which are the width of the external patch and the initial load.The test results indicate that the initial load has great effect on the ultimate load of the beams strengthened by the method,but the method can effectively improve the ultimate bearing capacity and the rigidity of the beams.Which can offer reference to similar projects.
