For verifying pile bearing capacity improvement by post-grouting on tip and side and the decrease of building settlement, 10 tip and side post-grouting and 2 unpost-grouting piles are tested by low strain dynamic test, static loading test, stess distribution monitoring and high strain dynamic test, and the building settlement is monitored. It is indicated that all piles length and integrity are meeting the challenge, the post-grouting piles bearing capacity are at least 70% improved than that of unpost-grouting piles, designing pile bearing capacity as 8800kN is safer, the building maximal settlement and the differential settlement is satifying. The preliminary designed 904 piles are reduced to 531 by adopting post-grouting technique and about 20% cost of pile engineering is saved, the proper grouting stata choosing, the accurate grounting volume and pressure controlling in the post-grouting constrution process are needed.
