| 摘 要： | 将灰色理论中灰色局势决策方法应用到某滑坡支护工程中优化预应力锚索的锚固角及锚索的钢绞线根数。采用Slope /W 软件建立滑坡剖面模型，将不同的锚固角度和钢绞线根数组合，以Janbu 法计算的安全系数和需要的钢绞线总长度为目标，采用灰色局势决策法，得到以锚固角35°，9 根15. 2 mm 钢绞线的预应力锚索加固该滑坡，能取得即安全又经济的效果。

| Abstract: | The grey situation decision method in grey theory is used to optimize anchorage angle and strand root number of prestressed anchor cable in a landslide support engineering． The authors use Slope /W software to establish landslide profile model through a combination of varied anchorage angles and strand numbers to calculate the safety factor and the total length of strand by Janbu method． Taken grey situation decision method，safe and economical effect are achieved when supporting landslide with 35°anchorage angle and 9 roots of 15. 2 mm strand． |

| Keywords: | landslide prestressed anchor cable grey situation decision optimum |
