摘　　要：通过14根模型梁的三分点加载试验研究,分析了掺加高效减水剂、粉煤灰、磨细矿渣和聚丙烯纤维对高性能混凝土梁正截面受力性能的影响,并将试验结果与有关混凝土结构设计规范的计算值进行了对比,初步验证了混凝土结构设计规范(GB50010-2002)对高性能混凝土梁的正截面设计计算的适用性,为大掺量外掺料高性能混凝土在工程上的应用提供了依据。This paper expounds an experimental study on the flexural behavior of high performance concrete beams with tests of fourteen specimens, and makes a detailed analysis and comparison of the flexural capacity of high performance concrete beams respectively mixed with superplastieizer, fly ash, fine slag, and polypropylene fiber. A comparison is also made between the test results and the theoretical values. The comparison preliminarily proves the applicability of the Design Code for Concrete Structures （GBS0010 -2002） to the design and calculation of the flexural capacity of high performance concrete beams, thus providing a basic test support for the application of high performance concrete with large quantity of mineral admixtures.
