| 摘 要： | 地铁换乘节点深基坑施工中需要使用超长以及斜钢支撑作为支护结构,其受力变形复杂,设计中若考虑不周,易出现压杆失稳而诱发工程事故。以实际工程为例,将三维设计技术应用于地铁深基坑斜长钢支撑设计过程中,利用三维仿真软件Inventor进行单层钢支撑结构模拟仿真,分析了基坑下挖过程中钢支撑内力与变形特征,为地铁深基坑支护过程中优化钢支撑结构的设计与施工提供技术依据。

Analysis of Steel Support Structure in Deep Foundation |
| |
| Abstract: | The construction of subway foundation pit at transfer station requires the long oblique steel support structure,whose strength and deformation are complicated.A flawed structure may lead to pressure bar instability as well as engineering accidents.Referencing real engineering practice,we applied three-dimensional technology in the design of structures of subway foundation pit.We leverage 'Inventor'3D simulation software;to simulate a single layer steel support structure and analyze its internal force and deformation characteristics during excavation. The result can provide a technical evidence for steel support structure optimization in subway foundation pit. |
