项目摘要
In this research, a soil improvement enhanced pile foundation has been studied. Bridge foundations made of RC,PC or PHC piles behave nonlinear during strong earthquake motions. The performance design has recently introduced for civil engineering structures against the damages. The honeycomb-shaped improved soil with the fill-in of used-tire shreds around piles works for reducing the foundation response. In the case of strong motions for the so-called Level 2, the damages at the honeycomb shaped WIB save the structural foundation by absorbing seismic energy.Computer simulation has been conducted for the honeycomb type WIB based on the finite element model. The 2-dimensional and 3-dimensional analyses are compared for the parameter involved. The internal forces in piles are focused as well as the deformation for the seismic safety consideration.
本研究对土壤改良强化桩基进行了研究。由 RC、PC 或 PHC 桩制成的桥梁基础在强地震作用下表现出非线性。最近针对土木工程结构引入了针对损坏的性能设计。蜂窝状改良土壤在桩周围填充废旧轮胎碎片,可减少地基响应。在所谓2级强烈运动的情况下,蜂窝型WIB的损坏通过吸收地震能量来保存结构基础。基于有限元模型,对蜂窝型WIB进行了计算机模拟。比较 2 维和 3 维分析中涉及的参数。出于地震安全考虑,重点关注桩内力和变形。
