【摘要】以某预应力混凝土连续梁桥为例,采用有限元计算软件,选定6个对连续梁桥线形控制有影响的因素,分析这些因素变化时,梁段节点标高的变化情况。并对各影响因素提出相应的控制建议,为相似桥梁的线形控制工作提供一定的借鉴。更多还原

【Abstract】 Taking a prestressed concrete continuous bridge as an example, using finite element software to analysis the girder nodes’ elevation subsequent change when six factors change which are related to continuous bridge’s geometric control. The corresponding control proposals are proposed for each influencing factors in order to provide some reference for the similar bridges’ geometric control work.更多还原
