Results show that the slip displacement of the continuous beam on the middle support is equal to zero, but the slipstrain is not.
结果表明：连续梁在中支座处虽然滑移为零，但滑移应变不为零；

The method not only can consider behavior of stress strain of soil, but also can determine the most dangerous slip surface and its factor of safety at any time.
该方法不仅能够考虑土的应力应变性质，而且能够在任意时刻确定最危险滑动面的位置及安全系数。
