Abstract

This study investigates the vibration screening efficiency of geofoam-infilled (GB) and open trench (OB) wave barriers. Field-scale vibration tests are conducted to evaluate the performance of different barriers under active and passive screening conditions. A modular panel-based system is adopted for the GB to facilitate easy installation, uninstallation, and reinstallation. The impact of input frequency, source-barrier distance, and measurement direction on the performance of GB and OB is thoroughly examined. The results indicate that both barriers perform satisfactorily under different screening conditions, with superior effectiveness observed under active screening. For active screening, the performance of barriers improves with decreasing source-barrier distance. The screening efficiency of GB and OB is higher along the centerline than along the angular line. The performance of OB and GB improves with increasing input frequency for both active and passive screening techniques, irrespective of the source-barrier distance. Additionally, simplified design expressions are developed to predict the performance of GB under active and passive screening conditions. The predicted outcomes of the proposed expressions compare well with the findings reported in the literature.

连续板型土工泡沫填波障隔振特性的大型现场试验

本文研究了土工泡沫填充（GB）和开槽（OB）两种挡波材料的隔振效果。通过现场振动试验，评价了不同屏障在主动和被动筛分条件下的性能。GB采用模块化面板系统，便于安装、卸载和重新安装。深入研究了输入频率、源垒距离和测量方向对GB和OB性能的影响。结果表明，两种屏障在不同的筛选条件下均表现良好，其中主动筛选效果更佳。对于主动屏蔽，屏障的性能随着源-屏障距离的减小而提高。GB和OB沿中心线的筛分效率高于沿角线的筛分效率。在主动式和被动式筛选技术中，无论源障距离如何，OB和GB的性能都随着输入频率的增加而提高。此外，还开发了简化的设计表达式来预测GB在主动和被动筛选条件下的性能。所提出的表达的预测结果与文献报道的结果相比较。

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.
