Refined three-dimensional model of concrete cutoff wall in deep overburden for dynamic numerical simulation

File 1 dataset contains the input Seismic wave time history. File 2 dataset provides the normalized modulus attenuation and damping ratio curves. File 3 dataset details the axial displacement distribution at the cutoff wall crest under full-reservoir conditions. File 4 dataset shows the displacement distribution along the medial axis under full-reservoir conditions. File 5 dataset presents the time history of tensile stress development on the downstream side under seismic loading. File 6 dataset illustrates the time history of compressive stress development at various locations of the cutoff wall under seismic loading. File 7 dataset depicts stress distribution along the wall height at the medial axis (coarsened area) under seismic loading. File 8 dataset shows the time history of tensile stress development in the dense mesh area (weak area) on the downstream of the cutoff wall with different subdivision methods under earthquake.
