| Geological disaster is a type of natural calamities, which is not only a natural phenomenon but also a social economical phenomenon. Besides the natural factor, the main reason to the serious geological disaster is that destroyment of the growing population, exploiting natural resource. And the stability of man-made slope relating to many fields of engineering is an important research.Firstly, the dissertation reviews the research history of the stability of slope and analysis the background of regional geology and believes that the cause mechanism of geological disaster and the history ways and synthesis ways of harness must enhance; secondly, the article discusses the theory and ways of the stability of slope, and points out that qualitative ways, quantitative ways and undetermined ways must be put to man-made slope practical use; thirdly, the article studies the design of strengthening harness and the ways of construction in the slope , and puts forward the optimum design of construction and take combined ways to strengthen man-made slope which guards against the worst position and is economical and safety, it has the directive function to the similar engineering. |
