AB  - There are numerous landslide sections along the railways of the Soviet Union that have been investigated to varying degrees. As one of the measures for landslide control, deep drainage has come into widespread use and, in many cases, constitutes an essential component of comprehensive slope-stabilization works. Deep drainage systems have already been implemented in major landslide areas such as Batraki, Oka, Ulyanovsk, Uvek, and Knyazev. Approximately 30 kilometers of drainage curtains have been constructed in these projects. A number of other large landslide sections still require dewatering, and deep drainage works are also planned for these sites.From a structural standpoint, the most widely used system is combined deep drainage, consisting of vertical wells or boreholes connected with drainage tunnels. The latter serve both water-conveyance and drainage functions.In a number of projects, tunnel construction personnel were confronted with serious support deformation problems. These deformations necessitated repeated replacement of tunnel supports long before the facilities were commissioned. Moreover, support deformation continued even after the tunnels entered service, and in some cases reached considerable magnitudes. For example, in one tunnel at Uvek Station, by the sixth year of operation, 50% of the installed reinforced-concrete frames had become deformed. Deformation on such a scale inevitably leads to a sharp increase in tunnel operation and maintenance costs. The tunnel support at Uvek was designed on the basis of rock pressure calculations determined according to the method of Professor M. M. Protodyakonov. This method has received the widest recognition and has proven effective in many practical applications. However, in the drainage tunnels at Uvek and Knyazev, the supports still experienced deformation despite the use of substantial safety factors in the calculations, because the actual rock pressure considerably exceeded the calculated values.
