Problems solved by technology
Considering the microcosm of the composite pavement, it contains grains of more than one chemical composition; due to the existence of this uneven microstructure, the stress distribution and deformation distribution after loading are uneven; for larger deformation There may be a risk of cracking and failure in the position. If it is applied to the road, it may cause circuit failure in the road and form a road safety hazard.

The invention discloses a load-bearing deformation failure risk assessment method and design method for a composite pavement. The assessment method comprises the steps: building a composite pavement finite element model and a wheel finite element model, and carrying out the assembling operation; loading a preset displacement load to the wheel finite element model, and solving a deformation distribution result of the composite material pavement finite element model; if the maximum value of the deformation of the composite material pavement finite element model exceeds a preset pavement permissible permanent deformation, determining that the composite material pavement has a risk of bearing deformation failure under the displacement load. By means of the method disclosed in the scheme, whether the composite material pavement has the bearing deformation failure risk or not can be evaluated, data support is provided for finding out the safe composite material pavement for road design, andthe possibility of road safety risks is reduced.
Description
technical field [0001] The invention relates to the technical field of roads, in particular to a load-bearing deformation failure risk assessment method and a design method of a composite material pavement. Background technique [0002] Photovoltaic roads or smart roads, which are the future development direction of roads, usually include light-transmitting road surfaces, photovoltaic modules that convert solar energy into electrical energy, and road bases. Among them, the light-transmitting pavement is used for laying intelligent pavement, which has the effects of high light transmission, impact resistance, and friction resistance. Obviously, the traditional asphalt / concrete pavement does not meet the high light transmission requirements of the light-transmitting pavement, and it is urgent to pay attention to the research and development of the light-transmitting pavement. [0003] Based on the consideration of road surface friction, the pavement materials of photovoltaic ...
