摘要
本文试验研究了用强度较高的混凝土置换正截面破坏的钢筋混凝土梁两根，用钢筋和强度较高的混凝土置换斜截面破坏的钢筋混凝土梁三根。在本试验条件下，修复后梁上新旧混凝土结合性能良好，修复后梁的承载力比原梁有所提高。
This paper describe the tests of two damaged beams which are ampered with high sconcrete and the shearing daznaged beams which are reopred with reinforce and high strigth concrete.Ih this test, the bond between new and old concrete in the repaids beams are good. The strength of repaids beams is higher than that of original beams.
