New method for accurately estimating physical and mechanical parameters of geotechnical material

Abstract

The invention provides a new method for accurately estimating physical and mechanical parameters of a geotechnical material, which comprises the following steps: acquiring prior gene characteristics: acquiring historical big data of physical and mechanical parameters of geotechnical materials in different areas and different groups, and performing statistical analysis according to the historical big data to obtain prior gene characteristics; carrying out posterior gene feature establishment: carrying out statistical analysis on physical and mechanical parameter test values of the newly added geotechnical material obtained in specific engineering detection to obtain posterior gene features; and accurately estimating the values of the mechanical parameters of the geotechnical material, namely accurately estimating the values of the corresponding parameters by using a Bayesian estimation method based on the prior gene characteristics and the posterior gene characteristics. According to the method, by means of the biological concept, the two concepts of the gene feature and the gene map of the geotechnical material for describing the overall physical and mechanical characteristics of the specific geotechnical material in a certain space range are put forward for the first time, and the prior gene feature and the posterior gene feature are combined; and the Bayesian estimation theory is used for rapidly and accurately estimating the geotechnical material parameters, so that the parameter estimation efficiency and precision are improved.
