摘　　要：随着城市化进程的推进,对高铁站和综合交通枢纽的需求日益增长。本文围绕新建铁路交通枢纽项目,应用钢-混组合结构体系以满足高承载力性能需求。通过一次二阶矩法(FORM)和蒙特卡洛模拟法对该结构体系的可靠度进行了详细分析,评估其在复杂荷载作用下的安全性和失效概率。此外,本文利用有限元模型对施工过程进行模拟,验证施工方案的可靠度。为实现大型构件的高精度吊装,采用计算机控制液压同步提升技术,确保构件在施工过程中的同步升降与安全性。研究结果表明,钢-混组合结构体系和液压同步提升技术为高铁站建设提供了有效的技术支持,可为同类型工程的设计和施工提供参考。With the advancement of urbanization,the demand for high-speed railway stations and integrated transportation hubs is rapidly increasing.This paper focuses on a newly constructed railway transportation hub project employing a steel-concrete composite structural system to meet the requirements for high load-bearing performance.A detailed reliability analysis of the structural system is conducted using the First-Order Reliability Method(FORM)and Monte Carlo simulation to evaluate its safety and failure probability under complex loading conditions.Furthermore,finite element modeling is utilized to simulate the construction process,verifying the reliability of the construction plan.To achieve precise hoisting of large components,computer-controlled hydraulic synchronous lifting technology is adopted,ensuring synchronized movement and safety during construction.The research findings demonstrate that the combination of steel-concrete composite structural system and hydraulic synchronous lifting technology provides effective technical support for high-speed railway station construction and serves as a valuable reference for the design and implementation of similar engineering projects.
