Abstract:
The relationship between the karst development features and the water gushes are presented in detail and assessment criteria is proposed; it is proposed that the karst water gushes are related to the atmospheric temperature, rainfall and rainfall intensity and the stress distribution caused by the construction; the water gushing mechanisms, such as the tensioning failure of the watersealing rock columns, the shearing failure of the fissures, the hydrodynamic expansion of the fissures and the stabilitylosing failure of the ground, are expounded by means of numerical analysis and theoretical analysis; the estimation of the water gushing quantity and the water gushing pressure, as well as the karst treatment technology, are presented.
