Engineering, The University of Western Australia, Perth, Australia Central South University Press and Springer-Verlag GmbH Germany, part of Springer Nature 2020 Abstract: In the context of deep rock... keeps increasing. In deep level, the rock mass or geological structure is inevitably subjected to high in-situ stress and the mechanical behaviors of rock mass are significantly affected [3]. Unlike......
J. Cent. South Univ. (2017) 24: 977-987 DOI: 10.1007/s11771-017-3500-2 Porosity of crushed rock layer and its impact on thermal regime of Qinghai-Tibet Railway embankment LIU Ming-hao(刘明浩)1, 2, LI...-Verlag Berlin Heidelberg 2017 Abstract: It has been proven that crushed rock layers used in roadbed construction in permafrost regions have a cooling effect. The main reason is the existence of large......

)04-1497-09 Revised RMR system on underground deep engineering rock mass property LIU Ye-ke, CAO Ping, YI Yong-liang, ZHANG Xiang-yang, CHEN Rui (School of Resources and Safety Engineering, Central South University, Changsha 410083, China) Abstract: Underground deep engineering rock mass has three distinct properties: high in-situ stress, high rock temperature and high groundwater......
and deep buried tunnels [7, 8], rock engineering under coupled high geostress and high groundwater pressure are commonly encountered. Excavation in such deep rocks increases the risk of some engineering... is also induced by excavation of surrounding rock with high ground stress in some deep rock engineering. The appearance of burst signals marks severe damage occurring inside the rock sample, heralding......
slope and deep rock engineering, pre- stressed bolt support is almost the only choice for maintaining the stability of the excavated high- steep slope, and high-strength pre-stressed bolts are often used in the anchorage engineering of deep fractured rock masses. Therefore, studying the mechanical properties and reinforcement effect of jointed rock masses with pre-stressed bolts plays a guiding......
is caused by tensile fracture from tensile strain although no tensile stress exists there. GONG et al [21] performed an on-site analysis of the rock failure phenomenon after the excavation of a deep... is controlled by the continuity and distribution of the natural cracks in the rock mass. At deep depths, the failure of a rock mass primarily depends on the stress around the tunnel caused by excavation......
