摘　　要：提出了一种利用反分析手段可以同时获取多个温度参数的立方体试验,并且从理论上证明了此试验反演参数的唯一性。利用这种试验方法不但大幅降低了试验费用,而且所得的参数和实际条件更为接近。The temperature parameters test, specially adiabatic test of concrete, needs higher cost and expensive special equipment. This paper introduced a test method-the cube test for temperature parameters, by which several temperature parameters can be obtained with back analysis. The feasibility of this test, identifiability and uniqueness of parameters are testified theoretically. By this method, the test expenditure is significantly reduced, and parameters also are more precise.
