A solid professional knowledge and a strict scientific attitude are the basic guarantee for scientific research. Nowadays, many problems appear in research papers of geotechnical engineering, which affect the paper quality and lead to unreliable results. This phenomenon has great influence. It not only wasted research resources but also led up to a false, impetuous research culture. The author analyzed widespread problems from the aspects of theoretical research, experimental research and numerical analysis, and verified them by examples, which provided full understanding about these problems to students and supervisors. Furthermore, supervisors need to be stricter in instructions to improve the quality of the graduate papers.
