Cause Analysis and Treatment Measures of Abnormal Bearing Capacity of Pile Foundation in a Project

Two pile bearing capacity tests have been carried out in a project, but the bearing capacity of test piles does not meet the design requirements. The geological factors and construction factors are analyzed, and the corresponding treatment measures are provided considering the aspects of construction technology and grouting technology on the basis of eliminating geological factors. Relevant measures are taken, and the bearing capacity of the third pile test construction can finally meet the design requirements. These measures have important guiding significance for the construction of large-area engineering piles, and also have important reference significance for the construction of post-grouting bored piles in similar thick sandy soil and silty soil.
