摘　　要：针对中国抗震和加固规范中存在的缺陷,为了提供基础性的试验数据,通过对15个试件(分5组)的试验进行研究,与以往的研究在浇灌方式、粘结材料、保护资源、锚固对象等方面不同。通过试验得出了不同灌浆料情况下的锚固长度,并且得出了L型复合灌浆料综合性能最好的结论。此研究成果为钢筋混凝土抗震规范等提供了重要依据,在工程中已被广泛应用。Aming at the defect existing in China＇s specification for quake-proof and reinforcing and in order to provide foundational experimental data, 5 sets of specimens（15） are tested in the dissertation. It＇s different from former researches in the way of pouring, sticky materials, thickness of protection course, object of anchoring and so on. We get anchoring length with different grouting materials .The conclusion is drawn that L type grouting material has greatest integrate capability. The research achievement offers important basis for the quakeproof specification of steel concrete, which has been adopted as the new code and used in some projects.
