行车荷载作用下软弱黄土路基的竖向应力特征

Characteristic of Vertical Stress in Soft Loess Subgrade under Driving Loading

采用线弹性体系理论和BISAR程序,计算分析了行车荷载下软弱黄土路基顶面和路基土中的竖向应力的变化规律,揭示了其分布特征,为软弱黄土地基公路工程的路基、路面设计提供了理论支持和决策依据。

Through the line elastic system theory and BISAR program, the article calculates and analyzes the varying regulation of the vertical stress in soft loess subgrade top and subgrade soil under the driving load, reveals its distributing characteristic, and provides the theoretical support and the decision-making basis for the design of the subgrade and the pavement of the soft loess subgrade highway project.
