3-D elastic analysis of vertical piles subjected to "passive" loadings
There are many cases where piles are subjected to "passive" loadings by soil movement past the piles. This paper employs a 3-D coupled boundary element approach to analyze the response of vertical piles subjected to passive loadings. A number of theoretical expressions for soil movements are developed acid presented. These expressions have been incorporated into the pile-soil governing equation previously developed by the authors. The analysis is employed to examine pile responses when subjected to some typical passive loadings, such as soil shrink/swelling, soil surface surcharge, tunnelling, soil movements arising from driving piles and cavity formation in soil. Reasonable agreement is found between some existing published solutions and those developed herein. (C) 2000 Elsevier Science Ltd. Ail rights reserved.
