Abstract The 2010 and 2011 Christchurch earthquakes proved that a shift is necessary in the current design practice of structures to achieve better seismic performance. Moreover, environmental concerns have prompted civil engineers to identify viable ways to reuse waste tyres through engineering projects. In this context, a multi-disciplinary geo-structural–environmental engineering project funded by the Ministry of Business Innovation and Employment is being carried out at the University of Canterbury in New Zealand. The project aims to develop a foundation system characterised by: (a) granulated tyre rubber mixed with gravelly soils to be placed beneath the structure, with the goal of damping part of the seismic energy before it reaches the superstructure; and (b) a basement raft made of steel-fibre-reinforced rubberised concrete (SFRRuC) to enhance the flexibility of the foundation under differential displacement demand. An overview of the material properties of the gravel–rubber and SFRRuC mixtures is also presented.

生态橡胶隔震基础系统：新西兰环境的可持续解决方案

摘要 2010 年和 2011 年的基督城地震证明，当前的结构设计实践需要转变以实现更好的抗震性能。此外，环境问题促使土木工程师确定通过工程项目重新利用废轮胎的可行方法。在此背景下，新西兰坎特伯雷大学正在开展由商业创新和就业部资助的多学科地质结构-环境工程项目。该项目旨在开发一种地基系统，其特点是： (a) 颗粒状轮胎橡胶与砾石土混合放置在结构下方，目的是在地震能量到达上部结构之前衰减部分地震能量；(b) 由钢纤维增强橡胶混凝土 (SFRRuC) 制成的地下室筏板，以提高地基在不同位移需求下的灵活性。还概述了砾石-橡胶和 SFRRuC 混合物的材料特性。
