Numerical modelling is able to solve the case with a complex geometry, precise calculation more parameters and quick calculation time. The use of this method needs to be validated due to a mismatch between the conditions of the numerical model with actual conditions in the field. Numerical modelling is done by distinct element method and one of the numerical validation methods is physical modelling in a laboratory. The geometry of the physical modelling in the laboratory using rock slope model with plane failure type as rock block object which will fail and using cement material. Physical modelling will be given load behind the slope using a pendulum as a seismic load with some variation of angles and be placing vibration test device (minimate III) above physical modelling to record the value of vibration due to a load of a given. Each test will be obtained the value of block displacement and vibration value. Based on this research, the results of numerical modelling approach value of displacement resulting from physical modelling test in the laboratory.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Complex geometries,Conventional methods,Displacement analysis,Distinct element methods,Numerical validations,Physical modelling,Rock block,Seismic load[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Numerical modelling,Physical modelling,Rock block displacement,Seismic load[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]This research This work was supported by laboratory of geomechanic and mining equipment, Institut Technology of Bandung, Indonesia.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
