Brief Discussions on the Test and Detection of the Slope Anchor of the European Mountain Tunnel
The commonly used protection form for the construction of the entrance slope of tunnels is the anchor and shotcrete structure(anchor rod,reinforced mesh and sprayed concrete).It is featured with simple construction,reasonable stress,timely protection,simple detection method,and easy to meet design requirements,therefore being the first choice for slope protection of tunnels in mountainous areas.The anchor on the side slopes of the tunnels on the North-South Highway in Montenegro have undergone a large number of pull-out tests according to European standards.The instruments and equipment used in the test,the test parameters adopted,the test steps performed and the data processing methods collected are all carried out in accordance with European standards,which has guiding significance for the anchor pulling and coring test process under European standards.
