其原因是坝体和基岩黏滞系数较大，坝体自重引起向上游变位的时效变形需要较长时间才能稳定；
Because the viscous coefficients of the dam and foundation rock are great, the time-dependent deformation caused by the dam self-weight leads to the dam upstream deformation stabilize in a long time;
研究结果表明，对于无约束的天然边坡，自重作用下其安全系数受流动法则的影响较小，而滑裂面的位置随流动法则的不同而不同；
The study indicates that the flow rule has small influence on the stability of the slope without restriction; however, the critical slip surface may be different.
