Roadbed rebound modulus testing method based on double-rear-axle inspection car
The invention discloses a roadbed rebound modulus testing method based on a double-rear-axle inspection car. A double-rear-axle eight-wheel van is used as the inspection car; meanwhile, rebound flexure detection of different flexure detection points (a wheel gap and a wheel inner side) of a roadbed is carried out; a formula shown in the specification is used for calculating roadbed rebound modulus of the different flexure detection points (the wheel gap and the wheel inner side) respectively according to rebound flexure values of the different flexure detection points and corresponding flexure coefficients; and an arithmetic average value of the roadbed rebound modulus of the different flexure detection points (the wheel gap and the wheel inner side) is calculated to be used as the rebound modulus of the measured roadbed. According to the roadbed rebound modulus testing method, a phenomenon that a standard car is not standard in a detection field can be effectively avoided; the roadbed rebound modulus is inversely calculated, and flexure detection results of the different detection points can be mutually proved; and a testing error, caused by the fact that wheel loads on the left and right sides of the inspection car are unbalanced, is overcome so that the roadbed rebound modulus detection is reasonable and accurate.
