分析了GC-测试的实际性能。本文用虚拟裂纹模型计算了缺口梁三点弯曲试验的稳定条件。结果如图1所示。不同混凝土质量的GC值是通过对切口梁进行稳定的三点弯曲试验确定的。本文的结果表明，Gcis受骨料质量、水灰比和混凝土龄期的强烈影响（图4-8）。
The practical performance of Gc-tests is analyzed. The conditions of stability for a three-point bend test on a notched beam are calculated by using the fictitious crack model. The results are presented in Fig. 1.Gc-values for different concrete qualities are determined from stable three-point bend tests on the notched beams. The results in this paper imply that Gcis strongly influenced by the quality of the aggregate, the water-cement-ratio and the age of the concrete (Fig. 4–8).
