What are ground anchors?
A steel bar is inserted through the wall of an excavation and is fixed into the soil or rock either through friction or via a grout. It retains the excavation wall via a waler plate threaded onto the anchor.
What’s the difference between soil nails and ground anchors?
Although soil nails and ground anchors are very similar, they have a different grouted length. Soil nails are grouted along their full length whereas ground anchors are only grouted along part of their length.
What’s the difference between active and passive ground anchors?
Active ground anchors are subject to post-tensioning, meaning they require no wall movement to provide restraint. Passive ground anchors are subject to no post-tensioning after installation meaning they required wall movement to start providing resistance.
How are ground anchors designed?
Design of ground anchors using the Bustamante and Doix (1985) approach considers the strength of the anchor as being the minimum of the steel bar strength, the adhesion between the anchor and the grout block and the adhesion between the grout block and surrounding ground. The strength of the interface between the grout block and ground must only consider the length of the grouted anchor beyond the active earth pressure wedge. Calculation of the strength of the interface between the grout block and steel/grout must also consider that only part of the anchor length is bonded. Ground anchors and soil nails designed with the Bustamante and Doix approach are designed using an empirical approach.
Answer 1: 5.6m
Answer 2: 395kN
What's this calculator used for?
This is a free calculator for Geotechnical Engineers to check the capacity and anchorage of ground anchors against applied earth pressure. This calculator uses the Net Available passive resistance method (Burland) & Eurocode 7. Using this Engineering tool the active earth pressures applied to a retaining wall are calculated. Drained water conditions are used & ground water level is taken as being at ground level.
