摘要

The super-long bored pile has several characteristics of bearing capacity which is different from the common pile foundation due to the large length-diameter ratio. This type pile is mainly affected by the length-diameter ratio, length of pile, beside soil of piles, bottom soil of piles, and material of the pile and construction technology. Different factors have various effects on its bearing capacity, and away from a larger degree of influence on the type of engineering. This paper studied the effects of various factors on the bearing capability of super-long bored pile by using the grey relational analysis method, and sorts the influence factors. This provided theory evidence for the design and construction of the super-long bored pile in the similar engineering, which has a certain reference value.
