The pile foundation in muddy soft soil is taken as the research object,and the static load compression test method is used to analyze the different deformation and failure characteristics of bored piles under different parameters during the stress process.The research shows that in the process of grouting operation,the fine flow and slow injection method should be adopted,which is beneficial to accurately control the grouting amount and ensure that it meets the preset grouting standard.It is necessary to closely monitor the displacement of the pile top in order to adjust the grouting pressure,flow amount and velocity.Under the condition of the same pile length,the increase of pile diameter can significantly improve the bearing capacity of pile foundation.This is because the larger pile diameter increases the cross-sectional area of the pile body,which can more effectively disperse the load.When the pile diameter and pile length remain unchanged,the maximum bearing capacity of pile 3 is 1.37 times that of pile 4.This difference is due to the fact that the pile 3 adopts a composite grouting technology,which significantly enhances the stability of the pile and thus improves its bearing capacity.
