The Study On The Wheel Track Slab Axle Load Conversion

Road is a new road which paved with a certain width of the wheel track of cement concrete slab at the wheel of the wheel track roller compaction frequency belt Because the characteristic of the hardening of the area is small, and environmental damage is small. maintenance and repair are easy with poor money. Because the structure of the whole type is shop, whith belongs to the open road. Therefore suitable for construction in traffic volume, high underground water level of the smaller rural and scenic spots. That can reduce the frost heave, were destroyed, and can be a very good and the combination of environment., and add a scenery to rural and scenic spots. Academics have made the design of road surface of the wheel track size, but is still the analysis of the load stress calculated according to the 100 KN standard axle load, it is not in accordance with the characteristics of rural traffic. In this paper, that based on the characteristics of axial load to determine the appropriate road design of the wheel track standard axle load at the rural roads traffic investigation. It was designed with multiple factors and multiple levels. don’t type coaxial load by finite element software used for the loading structure, multivariate regression, the result of the stress are not coaxial-round stress regression formula. Road traffic design of the wheel track on the non-standard vehicles must be converted into standard vehicle. In this paper, load fatigue not coaxial-wheel load and fatigue equivalent standard load, axle load conversion coefficient according to the principle of equivalent, the more accurate reflection of rural road traffic situation, wheel track road design method is put forward. Last bottom stress results of multiple models were analyzed, and the influence law of various influencing factors is analyzed, and main factor for the preliminary to design forseize the rapid and effective adjustment.
