Abstract

Abstract

Prestressed concrete pipes construction by hammer can produce high excess pore water pressure in deep soft soils because of violent disturbance and poor permeability of soft soil.Through analyzing the data of excess pore pressure in sites,it was analysed excess pore pressures distribution distance against the pile and along depth,and was also studied excessive pore water pressure change in different time of single pile construction.The analysis results show that the notable influencing range of single pile construction is about 17.5 times of the pile diameter,and the peak excess pore pressure does not necessarily appear at the end of the last section pile construction,and excess pore water pressure caused by the construction of single enhancement centrifugal pile dissipates faster than that induced by normal prestressed concrete,and 70% to 80% excess pore water pressure can be dissipated after 4 hours in the end of single pile construction.
