摘要:
为研究某公路路基结构下穿高速铁路桥梁设计和施工方案可行性,以该公路下穿高速铁路为工程应用实例,通过有限元分析软件MIDAS-GTS模拟施工过程,并结合现场实时监测对设计及施工方案进行评估。研究结果表明:不同施工阶段高速铁路桥墩墩顶的各方向附加变形均符合标准要求,公路路基结构下穿高速铁路桥梁设计及施工方案可行,沉降监测曲线与理论分析曲线较为吻合,通过仿真模拟来评估设计方案是可行的。
Abstract:
To assess the feasibility of the design and construction scheme for a road subgrade structure crossing beneath a high-speed railway bridge, this study took a real case where a highway intersects the railway line. The construction process was simulated using the finite element analysis software MIDAS-GTS, complemented by real-time monitoring data to evaluate the design and construction scheme. The results indicate that the additional displacements in all directions at the top of the high-speed railway bridge piers throughout the various construction stages comply with standard requirements. The proposed design and construction scheme for the road subgrade crossing beneath the high-speed railway bridge is deemed feasible, with the observed settlement monitoring curves closely aligning with theoretical analysis. Using simulation modeling to appraise design solutions in this context is thus deemed viable.
