Strategic Study of CAE 2017, Volume 19, Issue 6,   Pages 116-123 doi: 10.15302/J-SSCAE-2017.06.017

Abstract:

The main prospects of the urban underground development in China are a greater depth and a wider dimension. Advanced devices and technologies require the development of new materials. From the aspects of excavation mechanical materials, support materials, and environmental protection materials, this study summarizes the status of the main materials in use and the prospects of new materials. Aside from the strength requirement, an environment-friendly feature is the main requirement of new materials. Thus, self-healing, biological, and green support materials are demonstrated as future prospects.
