Abstract: The deflection of precast piles and excavation problems induced by pile driving are introduced through an engineering case of pile foundation treatment of a power plant. The treatment and effectiveness by use of prefabricated drains method to dissipate the excess pore pressure by pile driving are also introduced under the condition without external loads. The excavation problems of the main power house under high pore pressure is solved; and factors related with prefabricated drains to dissipate pore pressure are analyzed. The observed results and engineering practice show that the pile foundation treatment by use of prefabricated drains is fast and economic; and it employs no external loads, however, the treatment effectiveness relates with the horizontal drainage system.

Key words: pile foundation treatment, excess pore pressure, precast pile, prefabricated drains, excavation
