On November 15, 2019, at the invitation of the Prof. Hanlong Liu and Prof. Yang Xiao, the Prof. Jianhua Yin of the Hong Kong Polytechnic University visited Chongqing University, and gave an academic report for the topic of "Nonlinear Rheological Models of Clayey Soils and Their Applications" at 14:30pm-16:00pm in the No.1 Academic Report Hall.

During the report, Prof. Jianhua Yin gave a detailed description of the nonlinear rheological models of clayey soil and their application. First, he gave a brief introduction to soil settlement and creep by taking the Leaning Tower of Pisa and Kansai airport in Japan as examples. Then, Prof. Jianhua Yin introduced in detail modeling the time-dependent stress-strain behavior of soils in 1D and 3D straining and applications. Next, he explained the 1D and 3D EVP model proposed by Yin and Graham, which overcome the limitations of many other functional models. At last, Prof. Jianhua Yin introduced the new research on nonlinear creep and compression function, and gave the further research direction.

After the report, Prof. Jianhua Yin discussed with the teachers and students in detail about the theory and data in the report.
