A probabilistic model is developed to relate the compressibility of a soil deposit to blow counts obtained from standard penetration tests. The established relation is based on a variable proportionality coefficient, the value of which depends on the nature of the soil. The variations in the blow count and the proportionality coefficient are examined through the calculated statistical parameters, and it is found that these variations can be explained in terms of a normal probability distribution. The method of derived distributions is then used to develop a probabilistic model for predicting the total settlement in a compressible clay layer in terms of uncertain standard penetration test results and loads. The compression ratio is found to be well described by a normal distribution, and the total settlement is likewise well approximated by a lognormal distribution.
