Anchor (LEM)

Define the Anchor element for Slope Stability Analysis.

Applicable Modules:

Stiffness

Reinforcement Spacing

Anchor spacing in the (lateral) direction of the section thickness

Initial Diffusion Width

Specify the width to account for the diffusion effect of Anchor. Generally the width of bearing plate of Anchor is used. In case of no bearing plate, the diameter of Anchor may be specified.

Initial Diffusion Angle

Angle of stress distribution of Anchor installation which is obtained from tests. Generally, a value of 10-15 degrees is used.

Tension Force

Maximum tension strength (material) of Anchor.

Pull-out Force

Specify the pull-out test strength. If no test data is available, specify a value equal to or greater than the tension strength. The smaller of the tension strength and the pull-out strength is used as the reinforcing force.

Anchorage Length

Pull-out Application Method

AL Considered/Not Considered: If the fictitious anchor point lies beyond the failure surface, the reinforcing force of the total anchor length is considered. If the point lies within the failure surface, the reinforcing force is ignored.

AL Partially Considered: The reinforcing force proportional to the anchor length falling beyond the failure surface is partially considered.
