Ma Chunhui, teacher postdoctoral. After completing the master 's and doctoral studies and training in Xi 'an University of Technology, it has gradually formed a research idea that takes solving practical engineering problems as the research orientation, takes continuous-discrete numerical simulation, artificial intelligence algorithm, safety monitoring and detection technology as the core means, and takes revealing the meso-mechanism of rockfill materials and improving the disaster prevention ability of hydraulic structures as the fundamental task. During the period of studying for a doctorate, the applicant had visited the Graz University of Technology in Austria for one year.
