黄河石门至禹门口段高陡边坡稳定性分析研究

Study on the stability of high and steep slope in Yellow River section from Shimen to Yumenkou

边坡的稳定性是兴修水利工程必须考虑的问题。本文以黄河中游晋陕大峡谷南段石门至禹门口段两岸分布的高陡边坡为例,采用UDEC软件数值分析计算、赤平投影分析计算,对高陡基岩边坡的稳定性进行分析。结果表明,采用上述两种方法综合分析、多重计算,才能得出较为满意的结论。

The stability of the slope is the issue that must be considered in construction of water conservancy projects. High and steep slopes distributed on both bank of Yellow River midstream Jinshan grand canyon section from Shimen to Yumenkou are adopted as examples in the paper. UDEC software is adopted for numerical analysis and calculation.Stereographic projection is adopted for analysis and calculation. The stability calculation method of high and steep bedrock slopes is discussed. The results show that more satisfactory conclusion can be obtained through adopting multiple calculations with comprehensive analysis method.
