文章通过对埃塞俄比亚黑棉土各物理力学指标试验结果的分析,展开对影响黑棉土的承载特性、膨胀特性、收缩特性和强度特性等不同物理特性的研究,不仅指出了在进行穿越黑棉土公路路基设计和施工时应注意规避的问题,而且提出了相应的理论指导,具有较强的实用性,可为穿越黑棉土地区的公路工程设计和施工提供理论依据和参考。
Through the analysis of the physical and mechanical indexes of black cotton soil in Ethiopia, the paper studies the different physical characteristics that affect the load-bearing characteristics, expansion characteristics, shrinkage characteristics and strength characteristics of black cotton soils. The design and construction of highway subgrade should pay attention to the problem of avoidance, and put forward the corresponding theoretical guidance. It has strong practicability and can provide theoretical basis and reference for highway engineering design and construction crossing black cotton soil area.
