Embodiment Construction
[0079] The following is an example of a homogeneous earth-rock dam project, in which the height of the earth-rock dam is 12.0m, the width of the dam crest is 4.0m, the slope ratio of the upstream and downstream dams is 1:2, and the length of the dam crest is 48.0m. The present invention will be further described in conjunction with the accompanying drawings. The following examples are only used to clearly illustrate the technical solutions of the present invention, but not to limit the protection scope of the present invention.
[0080] The present invention improves a construction method of earth-rock dam material constitutive model based on deep learning and finite element method, and its construction process is as follows figure 1 , including the following steps:
[0081] Step 1. Establish a finite element model according to the size of the earth-rock dam material specimen, input the stress-strain curve obtained from the compression test for finite element calculation, ext...
