为了探寻与当前重载交通道路发展需求相适应的路基设计指标标准,本文结合最新研究成果及工程实践,分析了影响公路路基性能的主要因素,通过改善路基设计与使用状态的差异,采用接近道路实际工作环境的轴载标准及温度、湿度条件,研究路基动应力、应变与工作区深度变化规律,提出了适应不同交通条件及其使用状态的重载高速公路路基设计轴载与强度指标标准的建议值,供同行参考。
In order to find out the index of roadbed design index which adapts to the current demand of heavy traffic road development, this paper analyzes the main factors that affect the performance of roadbed with the latest research results and engineering practices. By improving the difference between the design and the use status of roadbed, The actual working environment of the axle load standards and temperature and humidity conditions, the study of subgrade dynamic stress, strain and working area depth changes, proposed to adapt to different traffic conditions and the use of the state of heavy-load freeway embankment design axle load and strength index standards Recommended value for peer reference.
