不稳定边坡 meaning in English

instable slope
unstable slope

2 . losing stability and failure of slope is a developing process . slope monitoring is the most effective method to achieve the information on slope stability
边坡工程的失稳破坏，都有从渐变到突变的发展过程，对于可能存在稳定问题的边坡，监测是获知其稳定与否、不稳定边坡的发展过程的最有效的方法。
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。
