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。
In the hydropower station approach road planning, design stage and before the big pieces of transport, the need to analyze and calculate the adaptability of the road and through. The impact of road transportation on asphalt pavement is mainly reflected in the aspects of equivalent shaft and axle load. In this paper, the axle load conversion of heavy road transportation is studied. The stress of asphalt pavement cement stabilized macadam base is analyzed by BISAR3.0 software Situation, put forward the requirements of the minimum thickness control of asphalt pavement for transporting heavy pieces. The research results have similar reference value for similar projects.
