Experimental and numerical modeling of anchors under seismic conditions

摘要

In the last few years there has been a growing interest in the seismic behavior of groundanchors. An example of its practical application can be found in the reinforcement of landslides. The currentarticle presents the results obtained from numerical models as well as from experimental tests. Thenumerical modeling is performed in PLAXIS, using 9 node triangular elements with total of 27 degreesof freedom. After the model is solved, the load-displacement curve is obtained. The procedure is donefor different soil conditions. The experimental trials are conducted by the authors using shake table. Thelast one is created (by the authors) for the sole purpose of this test. The obtained results are comparedto those from the numerical models. The diversity of the results is shown in series of graphs that takeinto account the overburden pressure, reference acceleration, water content and the bondlength anchordiameter ratio.
