Abstract：Research purposes: The accurate formula of the stability coefficient F, and the circular parameters xa ,yo , r of a circular land-sliding surface have been obtained from the Sweden circular slice method. There is an incomparable advantage compared to the traditional method.
Research conclusions: The formula of coefficient of stability F, is recovered by introducing two parameters L and s of controlling arc position and simplifying the integral sum. This computing method is simple and easy with the result closing to the results made from other methods. With this method, a reliable resolution of one side slope given parameters can be obtained in a few seconds, so this method has real significance and is worth adopting widely.
