Title: Determination of Bearing Capacity of Single Pile based on Seismic Piezocone Penetration Tests

The result of field test in KunShan and the calculated result which used the theoretical relationship mentioned above are compared. The results indicate that the analytical solutions agree well with the in-situ tests, which show that the applications of seismic piezocone penetration tests have wide range in the design of pile foundation.Read More
