岩质边坡稳定性及预应力锚固分析现状

本文首先对目前常用的各类边坡稳定性分析方法的主要特点进行了评述,包括定性方法类的历史分析法、工程地质类比法、图解法、专家系统法,定量分析方法类的确定性模型法,如极限平衡法,应力应变分析法;非确定性模型法,如可靠性分析法、灰色系统理论法及模糊综合评判法等;及两类方法结合而成的随机有限元法。其次,对预应力锚固边坡的设计及稳定性分析作了阐述。

A REVIEW ON STATE-OF-THE-ART ANALYSIS OF ROCK SLOPE STABILITY AND PRESTRESSING ANCHOR

In this paper, firstly, the main characteristics of currently used analysis methods of rock slope stability are reviewed, which can be classified into two categories: a) The qualitative analysis methods, such as nature-history-geology analysis method, engineering geology analog method, graphic interpretation, expert system etc.; b) The quantitative analysis methods including: a. deterministic model methods, such as limiting equilirium method, stress-strain analysis method; b. Undeterministic model method, such as reliability analysis method, gray system theory method and fuzzy-synthetic evaluation; and c. rendom finite element method which is the combination of deterministic and undeterministic methods. Secondly, the design and stability analysis ofprestressing anchored rock slope are elaborated.
