摘要:
为了确保顶升钢平台关键系统在运行阶段与安装施工过程中的安全性，对其关键系统进行了有限元分析，验证其在顶升、施工和提升3种运行阶段下结构整体的安全性。基于分析结果设计了一种高效的安装施工方案，利用有限元软件对关键构件进行了吊装验算，结合实际需求确定吊装时使用的钢丝绳规格，并对顶升钢平台关键系统开展了安装施工模拟分析。结果表明：顶升钢平台关键系统在施工阶段的应力和竖向位移最大，其最大值均在钢结构设计标准的限值之内，且线性屈曲分析的结果显示钢平台在5倍的设计荷载下才会发生失稳，结构整体的强度、刚度以及稳定性均符合要求；顶升钢平台关键系统的各个构件在吊装作业时应力与竖向位移均满足钢结构设计标准的要求；钢桁架在安装过程中结构整体的应力与竖向位移呈现逐步上升的趋势，但构件的最大应力和竖向位移值均远小于钢结构设计标准的要求，表明此安装施工方案具有较高的安全性，分析结果可为安装施工方案的编制提供理论依据。
Abstract:
To ensure the safety of the key system of the jacking steel platform during its operational phase and the installation and construction process, the finite element analysis of its key system was conducted and the structural integrity safety under three operational phases including jacking, construction, and lifting was verified. Based on the analysis results, an efficient installation and construction scheme was designed. Key components were hoisted and verified using finite element software, and the specifications of the steel wire ropes used during hoisting were determined according to actual needs. A simulation analysis of the installation and construction of the key system of the jacking steel platform was also carried out. The results show that the stress and vertical displacement of the key system of the jacking steel platform are the largest during the construction phase, and the maximum values are within the limits of the steel structure design standards. Linear buckling analysis shows that the steel platform will become unstable only under five times the design load, and the overall strength, stiffness, and stability of the structure meet the requirements. The stress and vertical displacement of each component of the key system of the jacking steel platform during hoisting operations are in compliance with the requirements of the steel structure design standards. The stress and vertical displacement of the structure gradually increase during the installation of the steel truss, but the maximum stress and vertical displacement values are far less than the requirements of the steel structure design standards, indicating that this installation and construction scheme has a high level of safety. The analysis results can provide a theoretical basis for the formulation of the installation and construction scheme.
