Analysis of Relationship between Pile Quality and its’ Bearing Capacity
Bored pile is one of the most widely used foundation forms in civil engineering. Relationship between pile quality and its’ bearing capacity is seldom been discussed. This paper introduces 8 bored piles in one storage tank project in Ningbo, of which 4 piles are done vertical load tests; the other four are done lateral load tests. Combined with their quality, the results reveal that when load is small, pile quality has much influence on pile bearing capacity. As soon as load is large enough to transfer to pile bottom, quality of concrete at pile bottom becomes the main factor that impacts pile vertical capacity, meanwhile pile horizontal bearing capacity mainly depends on pile length. Post-grouting is done to improve pile quality. It raises pile’s bearing capacity while reducing differential settlement at the same time.
