Abstract: The engineering property of the flyash foundation in Zhengzhou was introduced and the quality of PHC pile was tested by the static load test. According to the p~s curve in the static load test, the bearing capacity of pile on the flyash foundation was studied. Then its feasibility on the flyash foundation and the rationality of the standard value of ultimate lateral resistance of pile on the flyash layer were discussed.
