Department of Structures and Materials


Established in 1958, the Department mainly engaged in the research of structural and material issues related to the research, consultancy, inspection, and rehabilitation of hydraulic structures. The Department has provided services or consultancies for more than 100 large-scale hydro projects including the Three Gorges Project, the Xiaolangdi Project, etc. It has also won about 40 national or provincial prizes for progress in science and technology and a dozen of patents.

Consisting of 4 research sections, the Department has a staff of 46, including 1 academician of the Chinese Academy of Engineering, 11 professor-level senior engineers, and 18 senior engineers. Of the employees, 10 have a doctoral degree and 16 have a Master's degree.
