| 摘要： | The most recent tendencies in pavement engineering design are directed to the return of the use of fundamental mechanical principles of engineering to predict design life through the concept of damage. Damage is associated with the relation between (1) the number of repetitions a material can resist until failure and (2) the predicted repetitions the designer is expecting during a period of time. Generally, mechanical responses as strains, stresses, and displacements are used to calculate the number of repetitions until a specific failure. In rigid pavements, there are analytical solutions that range from simple Westergaard's closed-form formulas to complex numerical solutions (as discrete-element methods and finite-element methods). This paper describes work done to develop an additional option in the middle: models calibrated to have the simplicity of the closed-form formulas and the accuracy of the finite-element methodology. Those models were then included in a graphical user interface, which will be used as the structural response engine in local mechanistic-empirical (M-E) design software. |
