In this paper , a primary discussion is carried out on the limitation above mentioned and a method to determine the specific locus of key blocks is given 本文针对上述不足进行了初步探讨,并给出了关键块体具体位置的确定方法。
So , many key blocks obtained from this theory aren ' t true because the length of discontinuous surface is limited and the specific locus can ' t be determined 因此,由其得出的某些关键块体由于其结构面长度的有限性并不是真正的关键块体而且关键块体具体的空间位置亦不能确定。
The above analysis shows some results as follows : generally the discontinuities including bedding planes are favor to the stability of slope , which means that most of the slopes will not suffer large sliding failure ; most of the high slopes situated in the interest area are stable . however there are some potential unstable wedges which can be identified based on the key block theory ; some suggestions for reinforcing high slope are presented based on the stability analysis and environmental friendly consideration 结果表明:该区边坡岩体条件对边坡整体稳定性有利;区内高陡边坡以稳定及基本稳定为主,不稳定边坡较少,但潜在局部不稳定块体较多;依据边坡的工程地质特征及稳定性评价结果,对该区高陡边坡的防治提出了建议。
On the basis of appraising a traditional method , the method of the stereographic projection and proportionally stereographic projection of a solid volume , this paper has introduced such methods as determination of dominant discontinuities , kinematic tests for rock - mass failure modes , geometrical judgment of a removable block , and determination of a key block , extending perfecting the traditional method , and thus making it has better suitability or availability and practicality 摘要本文在评价用传统方法即赤平极射投影和实体比例投影方法分析节理边坡稳定性的基础上,结合具体工程实例引进了优势结构面的确定、岩体破坏模式的运动学判释、可移动块体的几何判定和关键块体的确定等方法,使传统方法得到拓宽和完善,从而具有更好的适用性和可操作性。
