摘要
岩质高边坡的稳定性除了受构成边坡岩体、岩石风化情况、坡脚和坡高、临空卸荷效应等因素的影响以外,主要受结构面的控制和影响。根据岩体地质条件对四川某工程存在的岩质高边坡进行分段,并运用赤平投影来分析各段边坡的稳定性。结果表明:赤平极射投影是一种有效的定性分析方法,对岩质高边坡的稳定性分析起到一定的作用,为高边坡的稳定性计算和支护设计提供有力的依据。
The stability of high rock slope in addition to constitute a rock by rock weathering,foot and the slope height,airport unloading and other factors beyond the control of the main surface by the structure and impact.Based on the rock an engineering geological conditions exist in Sichuan high rock slope segment,and the use of stereographic projection to analyze the stability of slope.The results showed that： stereographic projection is an effective method of qualitative analysis of high rock slope stability analysis play a role,for the high slope stability calculations and provide strong support design basis.
