Brittle mechanical characteristics of hard rock exposed to moisture

Abstract Rich groundwater content can produce a complex geological environment for underground tunnels. Therefore, the brittle mechanical characteristics of hard rock exposed by tunnelling in a moist environment are of great significance. Uniaxial tests and acoustic emission (AE) analysis of sandstone with respect to different moisture conditions are described in this paper. Moisture-controlled trends of the stress–strain relationship, mechanical parameter variation, maximum instantaneous AE energy, cumulative AE energy and macro crack behaviour were analysed in detail. In addition, X-ray diffraction and scanning electron microscopy were performed to analyse the fracture surfaces of rock at the microscale. Sandstone particles were found to be more likely to slip past each other at high moisture contents, resulting in increased plastic deformation and dissipation of internal energy. Increasing moisture reduces the brittleness of hard rock and the probability of rock burst. The results reveal the mechanical mechanisms cause moisture to affect brittle hard rock and can contribute to the improvement of the design and construction of deep tunnels.

About National Digital Library of India (NDLI)
NDLI logo

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
