| 摘 要： | 利用自己实测的轮胎接地压力分布，分析了重型货车不同轮胎，在不同胎压和不同负荷作用下，沥青路面结构层的力学响应．分析发现，相同型号不同花纹的轮胎，对路面结构的力学影响并不相同；不仅车辆负荷超载时对路面结构有不利的影响，当轮胎胎压超过容许范围时，即使负荷不超过额定轴载，对路面结构的不利影响也十分显著．

| Abstract: | Mechanics response of asphalt pavement under different tire types with different level loads and different tire pressure of heavy vehicles are calculated. As analysis results show, the stress response of asphalt pavement structure are different under the same type of tires with different tread patterns. Serions problems may arise when current vehicle loads exceed its standard load or current tire pressure exceed the limit value. |

| Keywords: | road engineering tire ground pressure distribution non-uniform distribution characteristic asphalt pavement |
