In this paper, the method of three dimensional limid balance analysis has been presented for stability analysis of slope. According to the principle of two dimensional analysis way, the calculation model and formula of safety coefficient have been deduced. At the same time, the way has been verified in practical engineering. Two results have been compared each other.It is discovered that the safety coefficient of three dimensional way is larger than that of two dimensional way. It is concluded that the three dimensional way is much better than the two dimensional way.
