... percent of the bolts in the powerhouse are reported to have failed and the walls of the cavern are continuing to converge, albeit at a slow rate since its completion in 2008. Plans are underway to stabilize this important underground structure. The cavern is located in the complex geological conditions...

... Abstract Convergence measurements are an essential part of monitoring methods in underground openings. They also provide important information about the mechanical behaviour of the rock mass in the framework of site exploration. In shafts a more accurate estimation of the deformation behaviour...

... location results with three methods are proposed and their calculation abilities are compared. The results show that computational accuracy of the second method is influenced by initial value and the third method has the global convergence; At last, the last two methods together are adopted for source...
