EPS土工泡沫对挡土墙振动缓冲作用数值模拟

The numerical modeling of EPS soil foam buffer effect to earth-retaining wall vibration

对在地震中破坏的实例挡土墙,提出EPS土工泡沫缓冲层设计,通过加设不同密度及厚度EPS土工泡沫提出两个方案,运用显式有限元分析方法,对其缓冲效果进行分析,得出了有设计参考意义的成果。

The EPS soil foam buffer layer design was proposed to practical example earth-retaining wall in earthquake damage, through extra reinforcing different density and thickness EPS soil foam, two planning was proposed. Its buffer effect was analyzed with explicit finite element analysis method, the achievements with design reference meaning was obtained.
