-saturated porous rocks ZHAO Chong-bin(赵崇斌)1, Bruce HOBBS2, Alison ORD2 1. Computational Geosciences Research Centre, Central South University, Changsha 410083, China; 2. School of Earth and Environment... instability problem in fluid-saturated porous rocks is no exception. Since this kind of instability problem has both the conventional (i.e. trivial) and the unconventional (i.e. nontrivial) solutions......
J. Cent. South Univ. (2017) 24: 720-725 DOI: 10.1007/s11771-017-3473-1 Effects of porosity heterogeneity on chemical dissolution-front instability in fluid-saturated rocks ZHAO Chong-bin(赵崇斌)1... Abstract: Homogeneity and heterogeneity are two totally different concepts in nature. At the particle length scale, rocks exhibit strong heterogeneity in their constituents and porosities. When......
model of soft rocks ZHAO Yan-lin(赵延林)1, 2, CAO Ping(曹 平)1, WANG Wei-jun(王卫军)2, WAN Wen(万 文)2, LIU Ye-ke(刘业科)1 (1. School of Resources and Safety Engineering, Central South University, Changsha 410083... plastic strain and visco-plastic strain. The result shows that instantaneous deformation modulus tends to increase with the increase of creep stress; soft rocks enhance the ability to resist......
J. Cent. South Univ. Technol. (2008) 15(s1): 025-028 DOI: 10.1007/s11771-008-307-1 Identification of structure and parameters of rheological constitutive model for rocks using differential... of a rheological constitutive model for rocks, a new method based on differential evolution (DE) algorithm combined with FLAC3D (a numerical code for geotechnical engineering) was proposed for identification......
J. Cent. South Univ. (2020) 27: 2822-2833 DOI: https://doi.org/10.1007/s11771-020-4512-x Core discing characteristics and mitigation approach by a novel developed drill bit in deep rocks ZHENG Min... discing often occurs in deep rocks under high-stress conditions and has been identified as an important characteristic for deep rock engineering. This paper presents the formation mechanism of core......
Geochemistry of Rare Earth Elements of Mesozoic-Cenozoic Sandstones in North Margin of Dabie Mountains and Adjacent Areas:Constraints to Source Rocks 王道轩1,李任伟2,岳书仓1,金福全1,刘因1,李双应1,孟庆任2 (1.Department... of 0.69 and (La/Yb)N of 11.1, which are similar to the Foziling and Luzhenguan Groups, and it implies that the latter may be the source rocks of the former. The Sanjianpu and Heishidu Formations have......
J. Cent. South Univ. Technol. (2011) 18: 1217-1225 DOI: 10.1007/s11771-011-0825-0 Petrological characteristics, geochemical feature and metallogenetic relation of alkaline-rich rocks in northwest..., James Cook University, Townsville, 4811, QLD, Australia ? Central South University Press and Springer-Verlag Berlin Heidelberg 2011 Abstract: The alkali-rich rocks, spreading along the suture zone......
Rare Earth Element Geochemistry on Magmatic Rocks and Gold Deposits in Shizishan Ore-Field of Tongling, China Xie Qiaoqin1,Xu Xiaochun1,Xiong Yaping1,Lu Sanming1,Chu Guozheng2 (1.School... geochemical characteristics of the magmatic rocks and gold deposits in Shizishan ore-field of Tongling were studied. Three types of the magmatic rocks have almost the same chondrite-normalized REE patterns......
Testing study of subcritical crack growth rate and fracture toughness in different rocks CAO Ping(曹 平), LI Jiang-teng(李江腾), YUAN Hai-ping(袁海平) School of Resources and Safety Engineering... displacement load relaxation method. The behavior of subcritical crack growth was analyzed for different rocks. The results show that lgKI-lgv relations of four kinds of rocks measured by this method......
Rare Earths of Magmatic Rocks in Yanshanian Stage in Adjacent Region of Anhui and Jiangxi Provinces, Jiangnan Uplift 岳书仓1,朱光1,周涛发1,袁峰1,侯明金2 (1.School of Resources and Environmental Engineering,Hefei University of Technology, Hefei 230009, China;2.Anhui Academy of Geological Survey, Hefei 230009, China) Abstract:The geochemical characteristics of rare earth elements of magmatic rocks......
