【摘要】 根据主动加固思想提出了有粘结体外预应力加固体系并简单的介绍了该加固体系的施工工艺,讨论了利用ANSYS进行有限元分析的相关高级技术,最后用通用有限元分析程序ANSYS模拟了一独柱连续刚构箱梁桥整个施工加固过程,分析了各个施工阶段桥梁的线形变化,通过与实际施工监控的结果对比分析得出应用ANSYS很好的模拟了桥梁加固的二阶段受力特点以及有粘结体外预应力加固方法的工程应用价值.更多还原

【Abstract】 Bonded and externally pre-stress reinforcing system is proposed according to positive reinforcing conceit and construction technique is simply introduced in the paper, and then advanced technology with relation to emulating analysis is discussed. Finally emulating whole reinforcing process of one continued-rigid box-beam bridge, analyzing changes of deflection at different construction step by finite element software ANSYS and comparing with actual monitoring results, perfectly emulating two-step stressed characters of reinforcing beam by ANSYS and actual application value of bonded externally prestess are found out.更多还原
