In view of existing situation that the test pile samples of pile foundation are less than expected, the parameters of the static cone penetrations tests are adopted to estimate the bearing capacity of single pile. Then we make testing statistics analysis by using this value and evaluate the pile foundation site. An evaluation method considering an engineering case is introduced.
Keywords: cone penetration test; silent piling; bearing capacity; reliability; evaluation
