Study on the Deformation Properties of Functionally Gradient Metro Tunnel Lining Structure
In this article, a literature review about FGMs and a new idea were presented. In the past few years, the concept of FGMs has been introduced in the geotechnical engineering; some scholars have done some research about it. On this basis, this paper provided a new idea about the future application of FGMs in geotechnical engineering. The results show that the functionally gradient lining structure can meet the deformation requirement when the elastic modulus is reduced in some positions. In other words, the functionally gradient lining structure can reduce the material cost greatly.
