| 摘 要： | 以邯郸市人民路—东环路全互通立交桥工程NE16～NE19匝道桥为背景,根据《城市桥梁抗震设计规范》(CJJ166-2011),对小半径城市立交桥梁抗震进行分析探讨。计算表明:考虑铅芯支座及滑动支座的非线性特性,各个墩柱在E2地震下的工作状态均处于弹性范围内工作,达到了设置减隔震装置的性能目标。

| Abstract: | Taking NE16～NE19 ramp bridge of Handan City Renmin Road-Donghuan Road Interchange Project as the background and based on Code for Seismic Design of Urban Bridges (CJJ 166-2011), the article analyzes and discusses the seismic performance of small-radius urban interchange. The calculation makes clear that the working status of each pier column is all within the flexible range under the earthquake E2 and satisfies the setup object of seismic isolation device performance by considering the nonlinear performances of lead core support and slide support. |
