With ultrasonics application during checking the large diameter cast-in-situ pile body, it is usually applied the statistical method of probability and PSD. This paper presents a converse probabilistic-analytical method, which can identify important anomalies, both strong and weak, during interfered situation. So the inhomogeneity in concrete pile may be ellectively distinguished. In order to ensure the capacity of bed rock support layer under large diameter pile, a test-in-situ is conducted to determine the compressive strength and shear force inserting rock of the support layer, so the compressive strength and modulus value of elasticity of bed rock tested will closely tally with the actual situation.
