摘要:

针对武陟至济源段上跨运营高速公路钢箱梁吊装工程,开展系统的稳定性分析与设计研究. 通过理论计算与有限元模拟相结合,依据相关规范标准,开展吊耳设计与选型、钢丝绳选型与验算、220t 和 800t 起重机的抗倾覆稳定性验算、支腿及履带处地基承载力分析及临时支撑体系的稳定性评估. 结果表明:220t 和 800t 起重机的抗倾覆力矩分别为 5 112kN·m 和 92 604kN·m,满足抗倾覆要求;吊耳和钢丝绳设计具备足够安全裕度,临时支撑体系的应力和变形均在相关规范和标准的允许范围内,且满足刚度要求.

Aiming at the steel box girder lifting project of Wuzhi—Jiyuan section across the operatingexpressway, the stability analysis and design research of the system are carried out. Through thecombination of theoretical calculation and finite element simulation, according to the relevantspecifications and standards, the design and selection of lifting lugs, the selection and checking of wireropes, the anti⁃overturning stability checking of 220t and 800t cranes, the bearing capacity analysis of thefoundation at the outriggers and crawlers, and the stability evaluation of the temporary support system arecarried out. The results show that the anti⁃overturning torques of 220t and 800t cranes are 5 112kN·mand 92 604kN·m respectively, which meet the anti⁃overturning requirements. The design of lifting lugsand wire ropes has sufficient safety margin. The stress and deformation of the temporary support systemare within the allowable range of relevant codes and standards, and meet the stiffness requirements.
