Geotechnical courses, including engineering geology, soil mechanics, foundation engineering and so on, have rich contents and strong practical features. Case teaching method has been introduced to teaching process of the courses. Based on the real engineering cases, case description has been written, which is closely linked to the engineering practice. Using engineering case teaching method, students practical skills are developed intensively. The study process is highlighted during the examination and evaluation of students. By means of the measures above, a relatively complete case teaching method system is established. In recent years, the teaching practices show that the case teaching method can achieve good results of solving the conflicts between class hours and teaching content, and training the practice ability.
