摘要
针对晋西地区工程建设开挖形成的不同高度的黄土边坡,通过工程类比法、反算法、文献资料法和计算对比法,确定了不同高度黄土边坡的最优坡率。结果表明:8 m高黄土(Q3eol或Q2eol)边坡最优坡率为68°和66°;16 m高黄土边坡最优坡率为56°;24 m高黄土边坡最优坡率为47°;32 m高黄土边坡最优坡率为42°;45 m高黄土边坡最优坡率为35°。研究成果可供研究区或其他类似地区建设工程提供参考。
The paper,combined with engineering practices in loess area of west Shanxi,through field investigation and measurement,laboratory experiments,numeric calculation,aimed at different slope height（8 m,16 m,24 m,32 m,45 m）,using analogy,anti-algorithm,literature and numeric calculation to carry out analysis and study,de-rived the optimal rate of loess slope with different height.The results have been used in construction projects of the area.It can save project investment,protect the geological environments in construction area,also provide refer-ence for similar construction projects in other areas.
