Analysis of the Influence of Reserved Soil Platform on the Deformation and Stability of Foundation Pit Retaining Structure in Deep Soft Soil Areas
In order to study the impact of reserved soil platforms on the deformation and stability of foundation pit retaining structures in deep soft soil areas,based on a specific deep foundation pit project in Changle Binhai,Fuzhou,finite element analysis method was used to simulate the excavation of foundation pits using reserved soil platforms.The influence of factors such as the presence or absence of reserved soil platforms and different soil platform sizes on the deformation and stability of foundation pit retaining structures was analyzed,and moni-toring data was combined for analysis.The research results indicate that as the width of the soil platform increases,the horizontal deforma-tion of the retaining pile decreases,and the overall stability of the foundation pit increases;As the height of the soil platform increases,the horizontal deformation of the retaining pile decreases,and the overall stability of the foundation pit increases accordingly;When the width of the soil platform is small/the height of the soil platform is small,the control effect of soil platform reinforcement on the horizontal deforma-tion of the retaining pile is significant.However,when the width of the soil platform is large/the height of the soil platform is large,the con-trol effect of soil platform reinforcement on the horizontal deformation of the retaining pile is limited.The reinforcement of soil platforms has an improving effect on the overall stability of the foundation pit.
