| Abstract: | By analysis of the results measured during the construction of a pile foundation,we studied the squeeze pressure in soft soil.The variance of squeeze pressure under a pile tip with depth of pile penetration,and its maximum influence radius are discussed,and compared with theoretical estimates.The influence of construction sequences is discussed,too.This view is put forward that there are maximum and steady values of soil pressure during the construction of the pile foundation.And it is explained theoretically.Combined with data of the pore water pressure,the influence of construction of the pile foundation can be analyzed further according to the principle of effective stress. |
| Keywords: | pile foundation construction squeeze pressure measured result theoretical estimate |
