用改进后的CSF算法对FWJ边坡进行了研究和探讨，算出了边坡的安全系数，并搜索出了潜在滑动面，得出了影响边坡稳定的主要因素、破坏机理和初步的支护措施。实践表明，笔者的做法是简便、合理、可信的，有进一步研究和应用的价值。

Through researching on a rock slope by the improved CSF methods,the paper works out not only the security coefficient of the slope but also its critical slip surface, the influence factors and slip causes. It is proved that the author's ideas and ways, which can be studied and applied，are easy, appropriate, significant and reliable.
