Determination of large diameter bored pile's effective length based on Mindlin's solution
Journal of Traffic and Transportation Engineering (English ed. Online), 2015 The calculation equation of large diameter bored pile's effective length is connected with its distribution of pile shaft resistance. Thus, there is a great difference between the calculation results under the different distributions of pile shaft ...
