摘　　要：借助ADINA这个大型的有限元软件,结合用于边坡稳定性分析的重度增加法,探讨了在实际边坡工程中的应用问题.通过算例说明了重度增加法与条分法得出的稳定性系数相差在3%左右,该法可应用于边坡工程的稳定性分析的.利用重度增加法时边坡的塑性区发展有一个明晰的过程,使寻求真实的滑动面成为可能.ADINA is used in combination with the gravity increase method to analyze the slope stability. Calculation shows that the result of safety factors gained by the gravity increase method is three percent more or less than the result of slice method, so it can be applied in actual slope projects. When we use the gravity increase method, we can find that the development of the district of plasticity has a clear process, which can help us to search for a reasonable slope surface .
