Damage Identification of Reinforced Concrete Components Based on Deep Learning Percussion Method
钢筋混凝土构件在现代建筑工程中占据重要地位,其损伤状态与建筑整体安全性息息相关。传统损伤检测手段主要依赖人工经验判断,在检测结构损伤时面临精确性与及时性不足的困境。本研究提出一种创新的基于深度学习技术的叩诊方法,通过整合声学信号与深度学习算法,实现了钢筋混凝土构件损伤状态的自动化精准识别。本文以钢筋混凝土剪力墙为研究对象,构建了涵盖多种损伤状态的剪力墙声学数据集,运用卷积神经网络(CNN)提取声学特征,再借助分类算法判别损伤状态。通过试验验证,所提出的基于深度学习的叩诊法在剪力墙构件损伤识别的准确性与效率方面表现优异,展现出优异的应用潜力与工程应用前景,为钢筋混凝土构件损伤识别领域提供了一种高效且无损的全新解决方案。
Reinforced concrete components play a crucial role in modern construction projects, and their damage states are closely related to the overall safety of buildings. Traditional damage detection methods mainly rely on manual experience for judgment, facing the dilemma of insufficient accuracy and timeliness in detecting structural damage. This study proposes an innovative percussion method based on deep learning technology, which achieves automated and precise identification of the damage states of reinforced concrete components by integrating acoustic signals with deep learning algorithms. Taking reinforced concrete shear walls as the research object, this paper constructs an acoustic dataset of shear walls covering various damage states, uses a convolutional neural network (CNN) to extract acoustic features, and then employs a classification algorithm to determine damage states. Experimental verification shows that the proposed deep learning-based percussion method exhibits excellent accuracy and efficiency in damage identification of shear wall components, demonstrating outstanding application potential and engineering application prospects. It provides an efficient and non-destructive new solution for the field of damage identification of reinforced concrete components.
