| 摘 要： | 综合运用MIDAS和ANSYS计算软件,对广东省内某大跨径连续刚构桥主桥墩顶块（0号块）在施工阶段和营运阶段的受力情况进行了空间仿真及其抗裂性能分析。研究结果表明,在施工阶段最大悬臂端荷载作用下,横隔板的人洞顶部、横隔板与底板的交界处、横隔板与腹板的连接处等局部区域均产生较大的拉应力。若采用C60混凝土,则不能满足04...

| Abstract: | By making use of MIDAS and ANSYS calculation software,space simulation and crack resistance performance analysis of piers top block（block 0） of a large main-span continuous rigid frame bridge in Guangdong province in the construction phase and operation phase.The results show that during the construction phase of the largest cantilever loads,the diaphragm hole at the top of manhole,the diaphragm and the bottom junction of the diaphragm and the web connections and other local area have a greater pull stress.The use of C60 concrete,which cannot meet the requirements of 04 specifications of the crack resistance;the use of new materials ＂structural steel fiber polymer concrete（SFPSC）＂ can fully meet the requirements of crack resistance. |
