All rights reserved.Geological and Geotechnical Investigation and Reinforcement of the Ancient City Hasankeyf in Turkey, is carried out by a private company under the control of General Directorate of State Hydraulic Works (DSI). In the related site on the cliffs there are huge rock blocks which might cause a serious damage to the environment and historic fabric around. Prior to the reinforcement and protecting studies of stronghold the controlled dropping of the blocks mentioned must be performed. Knowledge and prediction of the seismic effects will be caused by dropping of the blocks to the historic fabrics called” Orta Kapı” and “Küçük Saray” and keeping induced effects below the thresholds existing in the literature are crucially important in means of reducing the blocks sizes before dropping. During the dropping of blocks previously specified which are of numbers 2, 3, 6 and 24 respectively, probable induced accelerations at “Orta Kapı” and “Küçük Saray” are determined and then the verification of the acceleration values whether they remain below or above the thresholds limiting maximum allowable accelarations to prevent any damage might be caused, is done. When the acceleration values originate at the locations where the blocks are dropped are previously calculated, small samples of rocks are dropped, acceleration for unit mass is determined and used as a scale factor in subsequent calculations. Effective absorption factor on the route between the points where the blocks are dropped and the target, is evaluated by performing in-situ tests and induced amplitudes are calculated after the absorption is applied to the equations.
