    Abstract
  • Based on the elastic multi-layer theory and the principles of displacement equivalence, the influence of pavement structure parameters, aircraft load radius and main canding gear types on the equivalent modulus of elasticity of foundation(EMEF) was studied.On the basis of 126 kinds of representative pavement structures, the EMEF regression formula was established, and the accuracy of regression formula was verified by using the back calculation solution of equivalent modulus according to the elastic multi-layer theory.Analysis result indicates that when the aircraft load radius and mail canding gear types are considered, aircraft load radius ranges from 10 cm to 40 cm, and the calculation errors of the EMEFs are less than 4%.So the formula is extensional, simple and practical, the calculation result is accurate.
