Effect of geofoam as cover material in cut and cover tunnels on the seismic response of ground surface
文献摘要：
In recent years, special attention has been given to the effects of underground spaces and structures on the seismic response of adjacent ground. Nevertheless, to the best of the authors' knowledge, no method has yet been considered to reduce these effects in technical literature. The present study aims to investigate the role of geofoam as the cover material in cut and cover tunnels on the seismic response of the ground surface. For this purpose, a numerical study was performed using FLAC 2D, a finite difference software, and verified against previous studies. The effects of parameters such as the geofoam type, thickness of the geofoam blocks and interfaces between the blocks, on the ground surface amplification pattern were investigated. Parametric studies demonstrate that the geofoam has a strong potential to attenuate the seismic horizontal movements of the ground surface. As the thickness of the geofoam blocks is decreased, its attenuation ability is increased. It was also determined that the interface between the geofoam blocks plays a key role in the attenuation of the aboveground seismic responses. Based on the results, it was concluded that geofoam is a proper material to attenuate seismic amplifications at the ground surface, induced by underground tunnels.
