Abstract:Fracture accidents of vertical shaft lining in aquifer are introduced. Fracture mechanism of the shaft lining is obtained for the first time by modelling tests. Relationships between vertical additional force and depth as well as other influence factors are studied. Methods for preventing the shaft lining constructed in special strata from fracturing are suggested.
Keywords:fracture of shaft lining  vertical additional force  modelling test
