<p>Among different existing vibration isolation methods, open trenches is a technique that is commonly used for reducing the transfer of ground vibrations. Despite many benefits of such a technique for isolating ground vibrations, its primary disadvantage is its instability and lack of vibration isolation effectiveness apart from the stability of the trenches. To address these concerns, a new technique has been developed by the authors, which includes filling up these trenches with a group of hollow pipes in a specific pattern. This is a novel method for reducing ground vibrations by burying hollow pipes horizontally. Through the use of three-dimensional (3D) finite-element modeling, the effectiveness of such hollow pipes in decreasing ground vibrations generated by harmonic stress excitation on the ground surface was investigated. Compared to open trench and rows of piles, these pipe assemblages have been shown to be very successful in reducing ground vibration transmission while also addressing issues of instability and enhancing vibration isolation efficiency. A 3D dynamic numerical model is constructed in PLAXIS3D, and the findings are validated against earlier publications. Next, a comparison research study is conducted, with its focus between horizontal hollow and vertical pipe piles. Finally, a detailed parametric study is carried out to establish the effect of each of the wave barrier’s architectural, material, and loading elements on its vibration isolation effectiveness. Critical parameters are discovered and tuned to maximize the efficiency of this new technique.</p>
