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

Steps to reproduce
In this paper, the concept of over-stress area ratio is introduced to analyze the effect of mesh generation strategy of the numerical model of the cutoff wall. A three-dimensional numerical model of an earth-rock dam on deep overburden is established, and the mesh sensitivity of concrete cutoff wall is studied based on nonconforming element. The effect of variations in element thickness, dam height, and overburden parameters on its deformation and stress characteristics is discussed. The key technical path of refine modeling is proposed by changing the plane mesh size subdivision method.
