Based on the theory of solving over-determined equations with the least square method and parameters back analysis methods, this paper discusses the approach to quickly determine the compressive moduli of multi-layered soft ground. The approach contains CPTU tests data together with corresponding ground settlement data. The results of the compressive modulus are compared with data of laboratory oedometer tests and other situ tests. Comparisons of the results indicate that the compressive modulus determined with CPTU tests are twice as much as that measured in the laboratory consolidation tests and are in good agreement with that from CPT and SPT. When the compressive modulus from CPTU tests were used directly for design, it would be better in practice.
