Topological feature study of slope failure process via persistent homology-based machine learning

no code implementations29 Sep 2020 Shengdong Zhang, Shihui You, Longfei Chen, Xiaofei Liu

Using software UDEC to simulate the instability failure process of slope under seismic load, studing the dynamic response of slope failure, obtaining the deformation characteristics and displacement cloud map of slope, then analyzing the instability state of slope by using the theory of persistent homology, generates bar code map and extracts the topological characteristics of slope from bar code map.

Analysis of tunnel failure characteristics under multiple explosion loads based on persistent homology-based machine learning

no code implementations19 Sep 2020 Shengdong Zhang, Shihui You, Longfei Chen, Xiaofei Liu

The geometric, physical and interunit characteristics of the tunnel subjected to explosive loading are extracted, and the nonlinear mapping relationship between the topological quantity of persistent homology, and the failure characteristics of the surrounding rock is established, and the results of the intelligent description of the failure characteristics of the tunnel are obtained.
