超薄导电磨耗层道路融雪除冰技术分析

TECHNICAL ANALYSIS OF ROAD SNOW MELTING AND DEICING WITH ULTRA-THIN CONDUCTIVE WEAR LAYER

超薄导电磨耗层除冰技术是一种道路融雪除冰的新方法,对保障冬季冰雪路面行车安全具有重要意义。文中采用有限元方法对包含超薄导电磨耗层路面进行建模分析,研究路面结构在行车载荷和温度载荷下的力学响应。计算结果表明在温度和行车载荷耦合作用下,路面层内应力比两者单独作用略微增加,而应变相比于车载单独作用反而降低;随着环境温度的下降,路面结构层中应力及应变都会有所增加。

The ultra-thin conductive wearing layer(UCWL)de-icing technology is a new method for snow and ice removal on roads,which is of great significance for ensuring safe driving on winter ice and snow-covered roads.In this paper,the finite element(FE)method is used to model and analyze the road with an UCWL.The mechanical re⁃sponse of the road structure under traffic loads and temperature loads is studied.The calculation results show that under the coupling effect of temperature and driving load,the stress in the road surface layer slightly increases com⁃pared to their individual effects,while the strain decreases compared to the vehicle's individual effects.As the ambi⁃ent temperature decreases,the stress and strain in the pavement structure layer will increase.
