Stability Calculation Method of Slope Reinforced by Prestressed Anchor in Process of Excavation

Table 2

Anchor arrangement for slope excavation stages.

Anchor serial number	The height from anchor top to slope (m)	Height of each stage of excavation slope (m)	Anchor layer number in each excavation stage
I	2.0	4.0	1
II	4.0	6.0	1~2
III	6.0	8.0	1~3
IV	8.0	10.0	1~4
V	10.0	12.0	1~5
