Abstract (297) HTML (98) PDF (663KB)(10)
Abstract:
Based on the research results and practical experience in coal and gas outbursts in the coal industry over the last nearly 200 years, the authors have basically understood the research concept and method, development process of the research, present research state and existing key problems and explo...
TECTONIC STABILITY ANALYSIS OF THE KAX RIVER HYDROELECTRIC PROJECT AREA
WANG Cheng-hu, ZHANG Yan-shan, XIONG Yu-zhen, KONG De-hu
2008, 14(2): 135-140.
Abstract (244) HTML (161) PDF (238KB)(10)
Abstract:
This paper has studied the tectonic stability of a dam site for a large-scale hydroelectric project, and analyzed the regional geological tectonic setting, activity of faults, historical earthquakes, tectonic stress fields of the project area.The analysis indicates that the dam site of the hydroelec...
APPLICATION OF THE ANSYS SOFTWARE TO SOLVING COUPLING OF IN-SITU STRESS AND FLUID
WANG Lian-jie, SUN Dong-sheng, ZHOU Chun-jing, Wang Wei, ZHAO Wei-hua, WANG Hong-cai
2008, 14(2): 141-148.
Abstract (171) HTML (78) PDF (267KB)(14)
Abstract:
The coupling of the in-situ stress and fluid is the research focus in recent years and also an important subject in research on rock and soil engineering and geology.So it has prominent significance to find out a simple method to solve the stress-fluid coupling equation.In this paper, a simple metho...
3D GEOLOGICAL MODELING OF COMPLEX LANDFORMS BASED ON FLAC3D
WANG Ji-lin, DING Chen-jian, WU Sheng-lin
2008, 14(2): 149-157.
Abstract (289) HTML (108) PDF (926KB)(13)
Abstract:
With respect to the problem of numerical modeling for simulation in conditions of complex lan dforms and geological structure, the idea of modeling from the part to whole was put forward based on the FLAC3D platform.Using the primitive mesh shapes of brick and tetrahedron, a 3D model of the geologic...
EFFECTS OF STRAIN-SOFTENING DILATANCY ON PROGRESSIVE DEFORMATIONS AND PRECURSORS TO FAILURE OF ROCK WITH INITIAL RANDOM IMPERFECTIONS
WANG Xue-bin
2008, 14(2): 158-167.
Abstract (217) HTML (94) PDF (424KB)(6)
Abstract:
For rock specimens with initially random material imperfections in uniaxial plane strain compression, the effects of shear dilatancy on the failure precursors and deformational characteristics are modeled using FLAC.For compact rock elements exhibiting the linear strain-softening behavior after the ...
COMPREHENSIVE TESTS AND APPLIED STUDIES OF HYDRAULIC FRACTURING IN THE ROCK MASS OF THE YANGJIANG PUMPING STORAGE POWER STATION
WANG Hui-ming, WANG Zhu-jie, DAI Bing-guo
2008, 14(2): 168-175.
Abstract (256) HTML (140) PDF (275KB)(8)
Abstract:
The surrounding rocks of the water tunnel of the Yangjiang pumping storage power plant are required to bear a maximum static pressure of 7.83 MPa; therefore, the state of in-situ stress, dead loadbearing capacity of surrounding rocks and high-pressure permeability are all essential data for the scie...
