Comparison and analysis of conversion methods for self-balancing test of pile bearing capacity

The principle and method of self-balancing test are introduced briefly. In this article, through comparison common Q-S curve equivalent transformation to transform from the balance measured load-displacement for traditional load - displacement curve, puts forward advantages disadvantages each, three bored piles in static pile reaction detect vertical compressive ultimate bearing capacity single is line with requirements compare after conversion. Some problems engineering pointed out, which certain reference value popularization application capacity.
