基于Midas的钢平台有限元分析与安全评价

Finite Element Analysis and Safety Evaluation of Steel Platform Based on Midas

为保证桥梁水上桩基施工的顺利进行,搭设水上施工钢平台是最常用的方法。以某高速公路跨河桥桩基施工钢平台为背景,基于Midas软件对钢平台进行有限元建模分析。再根据分析计算结果,对钢平台结构进行安全性评价。研究结果表明:该钢平台各杆件强度、刚度和稳定性均满足要求,钢平台结构是安全的。该Midas建模分析方法可为类似的工程结构建模分析提供参考。

In order to ensure the smooth construction of bridge aquatic pile foundation,the erection of aquatic construction steel platform is the most commonly used method.This study takes the steel platform for pile foundation construction of a river-crossing bridge on an expressway as the background,carries out finite element modeling and analysis of the steel platform based on Midas software,and evaluates the safety of the steel platform structure based on the analysis and calculation results.The results show that the strength,stiffness and stability of the members of the steel platform meet the requirements,and the steel platform structure is safe.The Midas modeling and analysis method can provide a reference for similar engineering structure modeling and analysis.
