The analytical method is adopted in classical geotechnical engineering limit analysis method. It cannot involve the stress-strain behavior of soil and sometimes assumptions needs to be made in advance about the shade or location of the failure surface. It is not suitable for heterogeneous materials

especially the rock engineering. So its application still remains limited. With the development of computer and computing technology

the limit analysis finite element method was put forward. With the strength reduction or load increase

the stability safety factor and failure surface can be obtained directly at limit state. It is very practical for geotechnical engineering design. This paper studies the limit analysis finite element method and its application in the slope、tunnel、ultimate bearing capacity of foundations. Through a series of case studies

the applicability of the proposed method is clearly exhibited.
