Parameters Analysis on Construction Control of Precast Piles in Soft Soil Ground

摘要

Based on the precast pile foundation field test of the power plant, the distribution and dissipation of the excess pore water pressure induced by the construction of the precast pile are first analyzed after the plastic drain board driven in the soft ground. Then the influence factors of the distribution and dissipation of the excess pore water pressure are presented. Subsequently the quality problem of the pre-date driven pile caused by the construction of the precast pile is studied. The main control parameters of the precast pile construction under the complicated condition are provided, which will provide a reference for such similar projects.
