摘要
制作C60混凝土试件,采用人工方法在试件内部产生不同深度和长度裂缝,测试带裂缝混凝土试件的抗压强度,采用Matlab程序分析抗压强度的变化规律,得到基于混凝土裂缝长度和深度因素的抗压强度损伤劣化模型。利用BP神经网络验证了该模型的可靠性。
The C60 concrete specimens were made and the cracks with deferent depth and width wereproduced by man-made way, the law of compressive strength degradation of concrete specimens wereanalyzed by Matlab programme, then the degradation model considered depth and width of cracks wasattained. The reliability of it was proven by BP neural network.
