| Abstract: | The rock anchor foundation can be widely used for the practical engineering in the transmission lines of mountain areas.Aiming at the highly weathered granite,six representative field prototype tests about the rock anchor foundation were carried out for a 220kV electric power transmission line in Xijiang mountain areas.The tests mainly include the vertical uplift loading in order to obtain such parameters as the bearing capacity and the bond strength between anchor bar and concrete for design of the rock anchor foundation.Based on the testing results,the typical failure modes of foundations,and the load-displacement relations are obtained.The testing results indicate that the rock anchor can be applied in moderately and strongly weathered rock foundations with good economic benefit. |
