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��
