Shaking Table Modeling Of Seismically Induced Deformations In Slopes

dynamicallyinduced deformation of the model Fig 2 Slope model with accelerometers and displacement gauges 23 Slope models in testing Slope models consisted of uniform Toyoura sand with the mean grain size of 0174 mm and the void ratio between A 0605 and A 0974 In the preparation of the slope models

Feb 20 2021 In earthquakeprone areas special attention should be paid to the study of the seismic stability of rock slope Particularly it becomes much more complicated for the rock slopes with weak structural surfaces In this study numerical simulation and the shaking table test are carried out to analyze the influence of seismic excitation and structural surface in different directions on dynamic

Largescale Shaking Table Test on Seismically Induced Failure of Earthcore Rockfill Dam J Liu FH Liu amp XJ Kong technology to capture the deformations of the rockfills and the Fiber Bragg grating FBG improve the quality of the images in large scale shaking table model tests for sand slopes

Mar 01 2016 The same shaking table was later used by Seed and Clough to study the earthquake resistance of sloping core dams with model scale of 1300 and model height of 66 cm Tests were conducted on models with sandy outer shells and clay cores They concluded that sloping core dams were generally resistant to earthquake damage but strong shaking may

Mar 16 2021 Earthquake shaking table Wikipedia There are several different experimental techniques that can be used to test the response of structures and soil or rock slopes to verify their seismic performance one of which is the use of an earthquake shaking table a shaking table or simply shake table

Mar 30 2001 This paper describes the third of a series of six shaking table experiments conducted as part of ongoing research to evaluate the accuracy and applicability of the Newmark 1965 procedure for computing seismically induced deformation in slopes A cohesive model slope was shaken by two identical test motions in succession mimicking a situation that commonly occurs when a preexisting

Nov 05 2019 Shaking table tests were performed to investigate whether the coupling effect of rainfall and earthquake induces the loess slope instability The loess slope model was made by using the similarity ratio based on a real slope Artificial rainfall was carried out and then seismic waves were loaded step by step to adopt a large shaking table of 4ampx22176ampx2009m
