description The invention relates to a marine soft soil stress strain model modeling method based on high-order hyperbolic mapping. A three-axis mechanics test of marine soft soil under a plurality of confining pressure is carried out to obtain stress strain data corresponding to each confining pressure; first-grade mathematical characteristics and second-grade mathematical characteristics of actually measured data are concluded and a model core function is selected; then, a dependent variable mapping function and an independent variable mapping function are established and independent variables and dependent variables in the core function and the actually measured data correspond one by one; a curve parameter corresponding of a basic formula under each confining pressure is determined through single stress strain curve fitting; and a mathematical relation between each model parameter and the confining pressure is analyzed to obtain a model parameter expressed by the confining pressure, and a stress strain model of a mar
