The Monitoring and Analysis of the Baotong Temple Subway Station Foundation Pit Engineering in Wuhan

This paper has introduced the foundation pit supporting design and monitoring program of the wuhan railtransit line 2 at a phase of the project section of 20, the Baotong temple subway station, And also made a preliminary analysis for the monitoring results of geotechnical engineering foundation pit lateral horizontal displacement and strut axial forces. The result indicated: soil layer and rock layer in the process of foundation pit excavation in the lateral deformation degree level is large, and the state of the different soil lateral level have different deformation degree. Due to the relative to the rock soil lateral deformation is bigger, the supporting shown by the inside of the strut axial forces are also relatively large. So, for different formation, carries on the soil foundation pit support scheme should choose reasonable design for optimization purpose according to their different deformation properties, soil and rock strata can take on different support form to get to both safe and economic purposes.
