In order to detect and prevent the potential dangers of such occurrences in a timely manner, continuous […]
Testing of ground anchors

Testing of ground anchors
March 28, 2019Ground anchor is a bearing element used to transfer the forces from the structure to the soil or rock mass. Early use of anchors included the application of rock bolts in Poland in 1918 and later in Czechoslovakia in 1926. Anchors were first introduced into civil engineering in 1934 by the French engineer André Coyne […]
