摘要
为解决多跨连续刚构桥梁合龙顶推力求解的问题,依托某多跨连续刚构桥梁,推导不同温差条件下的合龙顶推力理论公式,并选取工程实例进行了有限元模型的验证,系统研究了基于一次性合龙方式的连续刚构桥梁合龙顶推力求解.
In order to solve the jacking force of multi span continuous rigid frame bridge, based on a multi span continuous rigid frame bridge, the final closure jacking force theory formula was derived under the different temperature condition. The engineering instance was selected and the finite element model was verified. Continuous rigid frame bridge jacking force based on a one time joining closure was studied in system.
