“…Obviously, the increase in the transmission path increases the energy dissipation. The pile body also plays a role of vibration isolation, that is, the pile foundation is effective in reducing the propagation of reflected waves from the soil-pile contact surfaces to the superstructure, especially in the high frequency range [15,16]. GA-BP model shows a high prediction accuracy when the vibration frequency is within the range of 20 Hz, and the prediction error gradually increases in the vibration frequency range of 20 Hz to 80 Hz.…”

The rapid development of subway construction inevitably leads to the subway lines traversing through or adjoining the buildings. However, current research primarily focuses on the train-induced ground-borne or building with shallow foundation vibrations, with a relatively limited investigation into the vibration pertaining to the building with pile foundation. A vibration analysis model of a building with pile foundation adjacent to a subway is established in this study using the finite element method, and the effects of various factors on the vibration of the building are analyzed, then the prediction of building vibration characteristics is also carried out by combining artificial intelligence methods. The results show that the building floor has an amplifying effect on the vibration acceleration level and Z-vibration level in the high frequency range, and the vibration energy attenuation at high frequencies is faster in the building with pile foundation compared to the building with shallow foundation. In the meantime, it shows that the GA-BP model is capable of effectively capturing the vibration characteristics of the building with pile foundation within the dominant frequency range. and the vibration of the building with pile foundation can be predicted not only by parameters such as train speed, soil and structure parameters but also by train-induced ground-borne vibration, which provides the possibility of simplifying the process of vibration prediction process and enhancing the practical application.

“…Several mitigation measures are available, including meta-materials (resonator, stopband), geogrid (stiffening of subgrade), geofoam or concrete-filled trenches, and ground improvements such as concrete and stone columns (Figure 13). Geosynthetic-based solutions are gaining popularity due to their sound performance as well as sustainable benefits [38,39]. Stiffening of the subgrade beneath a railway track using layers of geogrid also has the potential to reduce the vibration level at such sites.…”

Geosynthetic engineering has made significant advances during the past decade in the areas of manufacturing and practical applications. As a result, geosynthetics have become essential materials that facilitate construction, better improve short- and long-term performance, and reduce long-term maintenance costs in routine civil engineering projects. Geosynthetics are also being recognized as fundamental to sustainable infrastructure development as they reduce the carbon footprint generated by infrastructure development by minimizing the use of natural construction materials. Creative use of geosynthetics in geo-engineering practices is expected to continue to expand as innovative materials and products are becoming available. In this paper, we begin by discussing issues related to climate change. The sustainable benefits of geosynthetics are then presented by demonstrating the potential of geosynthetics to significantly reduce carbon footprints compared to traditional solutions. Finally, recent geosynthetic technologies have been introduced for use in transportation infrastructure. The pathway forward of the geosynthetic technology is also discussed from the view of sustainable infrastructure development.
