Abstract：Research purposes: The research is done on how to decide the thickness and characteristics of the slight segregated or serious segregated concrete on the end of column pile for the subgrade of Wuchang-Guangzhou Passenger Dedicated Railway.
Research results: The thickness and characteristics of the slight segregated or serious segregated concretes can be decided with the mass integrity of pile body made by reflection seismology. It can be seen from static test for single pile that the bearing capacity of the slight segregated or serious segregated concrete on the end of column pile is more than 2000 kN.
