FLAC强度折减法确定边坡安全系数的影响因素分析
Analysis of the Influential Elements Based on FLAC Strength Reduction Method to Determine Slope Safety Factor
【摘要】 以澳大利亚计算机应用协会的一个典型考题为例,从网格密度和边界范围两方面对安全系数的影响做了初步研究.结果显示,网格密度对边坡安全系数的计算有一定影响;如果计算得到的滑动面只要在边界范围之内,边界范围对安全系数的影响并不太敏感.
【Abstract】 Based on a typical exam of ACADS,some preliminary research has been done about the boundaries and the grid density on safety factor.The results showed that the grid density on the slope safety factor calculation has a certain impact.If the calculated slip surface within the boundaries,the safety factor is not very sensitive.
