Transient Impulsion (TI^™)

The TI^™ method checks the uplift of a fully detached rock block with the transient pressures in the open joints around it.

• transient pressures in the open joints under and around the block, computed with the same water-hammer solver as the TFM^™ method
• net force on the block in time from the pressures on all its faces and its submerged weight
• resulting block displacement computed step by step
• block ejected when its rise exceeds a critical fraction of its height
• complements the MDI and MQSI uplift methods
• available in the 2D and 3D DFN rock mass models
