On the basis of the generalized Hooke's law and the traditional geotechnical material elastic modulus E, two dimensionless physical mechanics parameters, R and η, are introduced to modify its constitutive model. Three kinds of pile and rock-soil interaction mechanical curves are analyzed. The modified constitutive model can reflect the related characteristics of three mechanical behavior curves. In order to verify the applicability of this modified constitutive model, the cast-in-place pile in soft soil area in Shanghai-Kunming high-speed railway was analyzed. The static load test of pile ...
