坡比值

通过野外调查，得出边坡自然坡比，最后通过最大自然坡比与边坡的关系，确立了未来边坡的最佳开挖坡比值。

Through field investi - gation , arrive at the slope than the natural slope , and finally through the largest na - tural slope and the slope than the relationship between the slope of the future to establish the best ratio of the excavation slope . ( 8 ) .

实例表明，一定时步后边坡最大位移对坡高的比值会快速增加，建议取该无量纲位移突变时刻对应的参数折减系数作为安全系数。

It was shown from two examples that the maximum displacement of the slope would increase rapidly after a certain time step . The strength reduction multiplier corresponding to that critical time step was suggested to be safety factor of the slope .
