聚合物混凝土蠕变模型研究

摘要

The study undertakes the four-point bending test on the bending creep features of the polymer concrete beam and the reinforced polymer concrete beam,concludes their creep curves,and undertakes the fitting for the test data by adopting various models,calculates the creep model parameter,and concludes the principle models or Kelvin-Brugers model can be consistent with the test result.%对聚合物混凝土梁和加筋加强聚合物混凝土梁的弯曲蠕变特性进行了四点弯曲试验,分别得到它们的蠕变曲线,并利用各种模型对试验数据进行拟合,计算出蠕变模型参数,通过比较分析得知幂律模型或Kelvin-Brugers模型都能够与试验结果相吻合的结论。
