摘要：
The effect described by the Euler formula for a flexible line being under tension and wrapping around a rigid support is experimentally proved to implement in the case of a nonrigid support being a ground base. Model and field experiments show essential rise in the load-bearing capacity of ground anchors with flexible tendon—E-anchors, owing to this effect. Equipment for installation of the anchors is designed and trialed. Using DEM, a 2D problem on the efficiency of the new anchors as a function of direction of pull out force applied to the tendon is solved. The E-anchors are supposed to be promising for the application in construction and operation of engineering structures.
