Abstract
Consolidation settlement induced by dissipation of the excess pore water pressure due to pilling in soft clay and negative skin friction caused by it were analysed. Piling or the pile driving process usually induces excess pore water pressure in the surrounding soil. When this excess water pressure dissipates later on after the pile driving process is complete, settlement of the surrounding soil takes place and a negative skin resistance along the pile surface develops, which is undesirable (Hosseini & Rayhani in Int J Geo-Eng 2017) []. In this paper, PLAXIS 2D is used to take into account the nonlinear consolidation behaviour of the soil. The pile driving process was defined and analysed in terms of the expansion in a cylindrical cavity. In general, the results based on the FEM method were consistent with the actual field measurements on site. However in response to the problem, the permanent solutions are worked on.
