| 摘 要： | 为保证邻近铁路规划影响区范围内的深基坑施工过程中,铁路高架桥及站房的安全,通过建立三维分析模型,对原基坑支护方案的变形控制效果进行评估,并提出了2种优化调整方案。针对优化后的基坑支护方案,根据施工进度设置计算工况,找出最不利工况进行变形分析,确保了铁路桥梁结构及站房的稳定,总结的经验可为类似基坑项目的安全设计提供借鉴。

| Abstract: | In order to ensure the safety of railway viaduct and station building during the construction of deep foundation pit in the area adjacent to railway planning impact area,the deformation control effect of original foundation pit support scheme is evaluated by establishing three-dimensional analysis model,and two optimization adjustment schemes are proposed.According to the optimized foundation pit support scheme,the calculation conditions are set according to the construction progress,and the most unfavorable conditions are found out for deformation analysis,so as to ensure the stability of railway bridge structure and station building in the city.The experience summarized can provide reference for the safety design of similar foundation pit projects. |
