摘要
岩体结构面的特征是影响岩质边坡稳定性的重要因素。本文以某岩质高边坡为例,通过野外实测和室内统计分析,找出边坡的优势结构面,然后在应用赤平极射投影初步判断岩质边坡稳定性的基础上,引入实体比例投影方法,对潜在不稳定岩体的规模作出评估,得出潜在不稳定岩体的体积和结构面的面积等要素,并进一步计算岩质边坡的安全系数。结果表明,实体比例投影结合赤平极射投影法能够较好地判断岩质边坡的稳定性。
The feature of rock structural plane is an important factor affecting the stability of rock slope. The dominate discontinuity plan is found by field survey and indoor statistical analysis. Based on the preliminary rock slope stability by stereographic projection method, solid orthographic projection method is introduced to assess the safety factor of rock slope. The results show that stereographic projection method combined with orthographic projection method can be used to assess the stability of rock slope.
