项目摘要
In this study, proposed is a foundation strengthening design, accompanied by the nearby soil improvement against earthquake damages. This innovative design method of pile foundations increases the horizontal resistance by the stiffened front soil and the high damped mechanism by its compound configuration. The details are the procedure that encompasses the foundation pile by honeycomb shaped soil improvement with scrapped tire shreds fill-in. Additional high damping effect is expected by using high viscous asphalt mixture with tire shreds.The computer simulation was carried out from linear analysis for traffic-induced vibration to nonlinear analyses in severe earthquake motions. In the latter situation, the proposed design lead to a partial damage allowed concept to escape from the total damage by energy absorption.The vibration mitigation effect by honeycomb shaped WIB was investigated by field test. The WIB cell wall is made of a pre-cast concrete. The tire shreds were filled inside cells. The source loadings are a shaker driving, a guided hamper hitting, etc. The field test proved that the honeycomb shaped WIB is very effective for vibration mitigation, more than several dB reduction, compared to conventional vibration mitigation procedures.
在本研究中,提出了一种地基加固设计,同时对附近土体进行抗震加固处理。这种创新的桩基设计方法通过加筋前缘土体增加水平阻力,通过复合结构增加高阻尼力。详细介绍了用废旧轮胎碎石填筑蜂窝状土体加固桩基础的过程。将高粘沥青混合料与轮胎碎石混合料混合使用,可获得附加的高减震效果。从交通诱发振动的线性分析到强烈地震作用下的非线性分析,进行了计算机模拟。在后一种情况下,所提出的设计引入了允许部分损伤的概念,通过能量吸收从整体损伤中逃脱。通过现场试验研究了蜂窝结构的减振效果。WIB细胞壁是由预制混凝土制成的。牢房里填满了轮胎碎片。现场试验证明,蜂窝状WIB具有很好的减振效果,与传统的减振方法相比,减振效果可达数分贝以上。
