Comprehensive Testing and Analysis of Stress and Displacement of Airport Runway with Faults Subjected to Dynamic Load
Several means are proposed testing displacement and strain of airport pavement under dynamic loads. At the same time, analysis and testing way are proposed to the effect of displacement and strain of road by pavement fault. Placing strain gauges in the wheels is a way to measure pavement load under engine wheel. Displacement and strain of pavement can be measured by covering up strain gauge before ward. Level degree should measured with section apparatus of level, and the detailed curve not only statistics average value of the pavement ought to be written and be conserved. Finite element software ANSYS is adopted for theory analysis. Made known by analyzing initially, in the situation of same other condition, there is approximately linear monotone increasing relationship between dynamic load coefficient and pavement undulation.
