| 摘 要： | 称重是大型结构物建造过程中的重要环节,通过称重获得结构物准确的质量和重心位置参数,这些参数对大型结构物移位、吊装等工序具有重要价值.本项目的大型模块在非滑道码头强夯土基础上建造,通过建立码头强夯土地基上结构物整体的有限元模型,对结构物的建造和称重过程进行分析,评估结构物的沉降情况,以保证整个过程的稳定和安全.

| Abstract: | Weighting is one of the important steps for large-scale structure construction process.The accurate quality and parameter for center of gravity are obtained through weighting,which have the significant value for large-scale structure displacement and uplifting processes.The large-scale modules are built on non-slipway tamped foundation.The structure construction and weighing process are analyzed and the structure sedimentation are evaluated by setting up the finite element model of the whole structure on the wharf tamped foundation,and the stability and security are ensured in the whole process. |
