Abstract
This paper presents the results of a numerical FEM (Finite Element Method) simulation of the formation of a rock failure zone in its initial stage of development. The influence of rock parameters, such as the Young’s modulus, Poisson’s ratio and friction factor of the rock in the contact zone with the working surface of the undercut anchor head, were taken into account. The obtained results of FEM simulations were compared with the results of field tests conducted in Polish mining plants extracting rock raw materials.
Highlights
The results obtained from the numerical tests are consistent in terms of trends with those observed during load capacity tests of tests anchors installed in concrete, e.g., [16]
The results obtained from the numerical are consistent in terms of trends ical parameters of the medium,tests such as modulus (E), in Poisson’s ratioe.g., (ν) and Couthose observed during load capacity ofYoung’s anchors installed concrete
The most pronounced effects were observed for the friction coefficient and
Summary
Numerical modelling modelling [1,2,3], together with experiments [4,5,6,7], enables a detailed understanding of the derstanding of the actual actual behavior behavior of of structures structures and and their their optimization. Among the important issues that are addressed in the topic high anchor pull-out force. Among the important issues that are addressed in the topic of of anchoring, one candistinguish distinguishthe theproblem problemofofestimating estimating the the load load capacity anchoring, one can capacity of of anchors anchors (working alone as well as in groups) depending on the effective anchorage depth (working alone as well as in groups) depending on the effective anchorage depth(h(hefef),), the the strength strength of of concrete, concrete, the the distance distance from from the the edge edge of of the the object, object, the the ratio ratio of of the the anchorage anchorage depth depth to to the the thickness thickness of of the the concrete concrete element element in in which which the the anchor anchor is is embedded embedded [1].
