铁路桥梁深水基坑封底方式变形实测及数值模拟

Deformation measurement analysis and numerical simulation of different bottom sealing methods for deep-water foundation pit of railway bridge

某新建铁路工程大跨连续钢构106,107主墩深水基坑计划采用不同封底方式进行施工。首先对107主墩数值模拟结果与现场实测结果进行对比分析,然后对106主墩基坑采用不同封底方式进行数值模拟,并将两种施工方式模拟结果进行对比分析。

The deep-water foundation pit of long-span continuous steel structure 106,107 main pier of a new railway project is planned to be constructed by different back sealing methods.Firstly,the numerical simulation results of 107 main pier are compared with the field measured results,and then the numerical simulation of 106 main pier is carried out by using different back sealing methods,and the simulation results of the two construction methods are compared and analyzed.
