Abstract

The present investigation includes experimental and ANN-based intelligent modeling to explore the dynamic interference effect of closely positioned vibrating foundations placed on unreinforced and geogrid-reinforced soil beds. Large-scale field block vibration tests are conducted on isolated and interacting block footings placed on prepared foundation beds at IIT Kanpur, India. The dynamic interaction of various combinations of two-footing assemblies is examined where one footing (active footing) is excited with dynamic loadings, and the other (passive footing) carries static loadings. The tests involve three eccentric force settings for four distinct footing combinations at different clear spacings and reinforcement conditions. The responses of both footings are recorded at different loading frequencies. The interaction effect is presented in terms of the transmission ratio plotted against the frequency ratio. Additionally, an Artificial Neural Network (ANN) model is developed using the recorded field datasets to anticipate the dynamic interference effect. The predicted outcomes of the ANN model demonstrate promising agreement with the experimental findings reported in the literature, indicating the reliability and robustness of the intelligent model.

土工格栅加固土层上振动地基与静力加载地基之间动态相互作用的大规模实验和 ANN 建模

本研究包括实验和基于 ANN 的智能建模，以探索置于未加固和土工格栅加固土基上的紧密定位振动地基的动态干扰效应。在印度坎普尔国际理工学院，对放置在准备好的基床上的孤立和相互作用块状基脚进行了大规模现场块状振动试验。其中一个基脚（主动基脚）承受动荷载，另一个基脚（被动基脚）承受静荷载。测试包括在不同间距和加固条件下对四种不同地基组合的三种偏心力设置。两种基脚在不同加载频率下的响应都被记录下来。交互作用效应以传输比与频率比的关系表示。此外，还利用记录的现场数据集开发了一个人工神经网络（ANN）模型，以预测动态干扰效应。人工神经网络模型的预测结果与文献中报道的实验结果一致，表明了智能模型的可靠性和稳健性。

期刊介绍： The range of products and their applications has expanded rapidly over the last decade with geotextiles and geomembranes being specified world wide. This rapid growth is paralleled by a virtual explosion of technology. Current reference books and even manufacturers' sponsored publications tend to date very quickly and the need for a vehicle to bring together and discuss the growing body of technology now available has become evident. Geotextiles and Geomembranes fills this need and provides a forum for the dissemination of information amongst research workers, designers, users and manufacturers. By providing a growing fund of information the journal increases general awareness, prompts further research and assists in the establishment of international codes and regulations.
