文章研究开发了一种性能优越、造价低廉、施工方便、适合农村民居使用的新型三维隔震墩,三维隔震墩以普通圆柱螺旋压缩弹簧为核心受力构件;介绍了隔震墩的工作原理、设计理论及制作方法,并进行了拟静力试验与竖向振动台试验。试验结果表明三维隔震墩竖向与水平向隔震性能十分优越,适合在高烈度农村地区推广使用。
The article researches and develops a new type of three-dimensional seismic isolation pier with superior performance, low cost, convenient construction and suitable for rural residential use. The three-dimensional seismic isolation pier uses ordinary cylindrical helical compression spring as the core force component. The working principle of the seismic isolation pier , Design theory and production methods, and quasi-static test and vertical shaking table test. The experimental results show that the vertical and horizontal seismic isolation of 3D seismic isolation pier is very superior and suitable for popularization in high intensity rural areas.
