摘要
高边坡是人类生存及工程活动中最常见最基本的自然地质环境之一。伴随着大
型工程建设,尤其是大型水利水电工程,露天开采工程及交通工程等向复杂环境、
复杂地质条件场地推进,与之相关的自然斜坡和人工高边坡稳定性问题显得越发突
出。目前,边坡地质灾害己经和地震、火山并称为当今世界三大地质灾害源,国家
和地方已经投入了大量的人力、物力和财力来进行这方面的研究和治理,边坡的灾
害防治问题越来越引起人们的广泛关注。
高边坡的稳定性受控于边坡所在岩土体的基本特性——地层岩性、地质构造、
岩体结构、坡体结构及水文地质条件等以及人为改造的程度——开挖高度、坡形和
坡度等,由于地质体的复杂性、多变性和不均质性,使得高边坡设计也十分复杂,
至今还作为一种特殊设计而无章可循。
本文以具体的工程实例——陕西府谷电厂高边坡整治工程为例,用瑞典圆弧法等
常规方法和 ANSYS 有限元两种方法对该高边坡进行了稳定性计算和分析,然后在此
基础上提出切实可行的加固措施——预应力锚索(锚杆)锚固。
本文的这些研究成果在具体的工程实际应用中取得了较好的技术经济效益,同
时也对其它高边坡治理工程起到了较好的借鉴作用。

A Study of High Slope Stability Analysis and Its
Reinforcement Measures
Abstract
High slope is the mon and basic geological environments of human survival
and engineering activities. With large-scale construction projects, especially large-scale
hydropower projects, opencast mining works and transport projects to plex
environment, complex geological conditions venues advance associated with the natural and
artificial slopes high slope stability problem is ing more acute. At present, the slope of
geological disasters has been and earthquakes, volcanoes and the world today as three major
sources of geological disasters, States and localities have invested large amounts of human,
material and financial resources to conduct research in this area and treatment, Slope the
prevention of disasters has aroused widespread concern.
High Slope Stability controlled rock slope where a basic characteristic –– lithology,
structural geology, rock structure, Singapore structure and hydrogeological conditions and
the extent of human transformation––excavation height, slope shape and slope, Due to
plexity, variability and heterogeneity, making high slope design is also very
complicated, so far, as a special design institution.
Based on specific project –– Shanxi Fugu high slo
