Abstract According to the construction technology process of pre-stressed pipe piles in geotechnical engineering，the phenomenon of static compression of pre-stressed pipe piles with axisymmetric constraints is analyzed，and the stress state of the surrounding soil is proposed. (1) First，the RMNLD strength criterion is introduced，which effectively describes the failure and yield characteristics of clay，sand，rock，and other geotechnical materials. Based on this criterion，a transformation stress method for a two-dimensional stress model with parameters p and q is proposed. (2) The soil around the pile is regarded as elastic-plastic material，and the hardening and softening processes of the soil are effectively described using the UH model. To enhance the failure description capability for various rock and soil types，the stress generalization of the UH model is achieved through the transformed stress method based on the RMNLD criterion，leading to the derivation of the corresponding three-dimensional soil constitutive equation. (3) A simplified analysis method is proposed to describe the static compression process of pipe piles，utilizing an exponential function of the distance-to-diameter ratio to represent radial displacement at a given radial distance. Leveraging the self-similar properties of the forces and deformations of the soil surrounding the pile，the relationship between the distance-to-diameter ratio and radial strain，volume strain，etc.，is established using the state parameter . The corresponding soil stress can then be determined using the aforementioned strain values as boundary conditions. The validity and applicability of the proposed method are confirmed through comparisons with predictions，test results，and numerical simulations.
