摘　　要：隧道边仰坡的施工常用的防护形式为锚喷结构(锚杆、钢筋网片和喷射混凝土)。其具有施工简便、受力合理、防护及时、检测方法简便、设计要求容易达到等特点,是山岭隧道边仰坡防护的首选。黑山南北高速公路隧道边仰坡的锚杆按照欧洲标准进行了大量的拉拔试验。试验所用的仪器设备、采用的试验参数、执行的试验步骤及所采集的数据处理方法均按照欧洲标准规定进行。研究成果对欧洲标准下锚杆拉拔和取芯试验工艺有指导意义。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.
