重大件公路运输轴重对沥青路面的影响分析

Impact analysis on axle load of heavy cargo transportation to asphalt pavement

在水电站进场道路规划、设计阶段以及重大件运输前,需要分析计算相关道路的适应性和通过性。重大件公路运输对沥青路面的影响主要体现在当量轴次和轴重两方面,本文研究了重大件公路运输的轴载换算,利用BISAR3.0软件分析计算了沥青路面水泥稳定碎石基层的应力情况,提出了运输重大件的公路沥青路面最小控制厚度要求。研究结果对类似工程具有参考价值。

Abstract＂ It is necessary to analyse and calculate road adaptability and passing ability before the planning and design of the approach road to hydropower station. The main impacts of heavy cargo transportation to the asphalt pavement reflect in the equivalent axles and axle load. This article studies axle load conversion of heavy cargo transportation and calculates the stress condition of the cement stabilized macadam base for the asphalt pavement by using BISAR3.0 and proposes the minimum thickness requirement of asphalt pavement for heavy cargo transportation. The research results have reference value for the similar projects.
