ACTIVE TECTONICS AND GEOLOGICAL HAZARDS OF THE XIDATAN-LAHSA SECTION ALONG QINGHAI-TIBET RAILWAY AND THE ASSESSMENT ON ITS ENGINEERING GEOLOGY
WU Yun-sheng, YI Ming-chu
2002, 8(2): 97-135.
Abstract (291) PDF (1385KB)(13)
Abstract:
Based on the field survey for hydrogeology and engineering geology along the Qinghai-Tibet Railway made in 1975~1977,consulting the results obtained recently by the other people,the active tectonics,geological hazards and the engineering assessment on the Qinghai-Tibet Railway are expounded in the p...
COMPARISON OF GEOSTRESS MEASUREMENT BETWEEN AE METHOD WITH STRESS RELIEF BY OVERCORING IN SILIN POWER STATION,GUIZHOU PROVINCE
WANG Xi-hai
2002, 8(2): 136-140.
Abstract (256) PDF (168KB)(7)
Abstract:
In order to study the stress condition of the underground area at Silin power station,Guizhou Province,which will be constructed,the geostress measurements by acoustic emission(AE) and stress relief methods are carried out here.The results show that the magnitude of maximum principal stress by AE is...
PHYSICAL EXPERIMENTS ON CONTINENT EXTENSIONAL STRUCTURES
ZHOU Yong-sheng, LI Jian-guo, WANG Sheng-zu, ZHANG Liu
2002, 8(2): 141-148.
Abstract (230) PDF (302KB)(12)
Abstract:
According to the theory that plastic flow of the lower layer (including lower crust and upper mantle lithosphere) controls upper layer (upper crust) deformation in the multi-layer lithosphere, the paper studies the physical experiments of extensional structures adopted ductile/brittle double-layers ...
FABRIC FEATURES OF QUARTZ AND STRAIN ANALYSIS ON GNEISSIC GRANITE PLUTON IN SHUANGHE, DABIE
LIU Qiang, YANG Kun-guang
2002, 8(2): 149-155.
Abstract (268) PDF (272KB)(11)
Abstract:
Systematic measurements are made respectively on the quartz C-axis fabric, biotite (001) cleavage fabric and 3-D strain analysis by quartz for gneissic granite in Shuanghe, Dabie. The results show that Shuanghe gneissic granite pluton is characterized by compression during its emplacement and the su...
STABLE ISOTOPE CHARACTERISTICS OF THE JIN CHANG GOU LIAN GOLD DEPOSIT IN INNER MONGOLIA AND ITS ORIGIN
ZHANG Chang-chun, WANG Shi-qi, ZHANG Tao
2002, 8(2): 156-164.
Abstract (307) PDF (328KB)(17)
Abstract:
The research on stable isotope is very important and useful for analyzing the origin of deposits.The H,O,C and S isotope of quartz mineral vein in gold deposit of Jinchanggouliang in Inner Mongolia inherits the characteristics of metamorphic rocks and magmatic rocks in the area.Their compositions of...
THE ANALYSIS ON THE DEVELOPMENT OF ALLUVIAL AND LAKE LANDFORM IN FEN RIVER DRAINAGE BASINS
HU Xiao-meng, FU Jian-li, LI You-li, MA Zhi-zheng, YANG Jing-chun
2002, 8(2): 165-172.
Abstract (309) PDF (243KB)(14)
Abstract:
It has been unclear how the landform in Fen River drainage developed in Quaternary until now.This paper reveals that there exist three alluvial or lake terraces in the edges of Fen River drainage basins since the middle-late Pleistocene.There are a succession of loess-paleosol unites accumulated on ...
PILOT STUDY ON THE COLLAPSES AND LANDSLIDES OF THE THREE GROGE RESERVIOR OF THE CHANGJIANG RIVER
YANG Dy-yuan, LI Xu-sheng, FENG Li-mei, JIANG Hong-tao
2002, 8(2): 173-178.
Abstract (197) PDF (180KB)(7)
Abstract:
There are 134 large-scale accumulations of the collapsed ladnslide along the bank slope of the Three-Gorge reservoir.Their formation related to the depp-dissection of the mainstream of the Changjiang River in the Three-Gorge area.The steep bank-slopes cracked and the fissured rocks collapsed.The col...
DESTROY CHARACTER AND COULOMB CRITERION OF ROCK SPECIMEN IN PSEUDO-TRIAXIAL COMPRESSION
YOU Ming-qing
2002, 8(2): 179-185.
Abstract (241) PDF (298KB)(13)
Abstract:
The relation is linear between axial supporting capacity of specimen and confining pressure,but the crack angle of specimen can not be given by Coulomb criterion.The axial supporting capacity of sections with angle around 45°+φ/2 is nearly the same based on the concept of cohesion and internal frict...
RETROSPECT AND PROSPECT OF FIFTY YEARS MINERAL DEPOSIT IN CHINA
ZHANG Hui-xu, LU Chun-rong
2002, 8(2): 186-192.
Abstract (206) PDF (185KB)(11)
Abstract:
This paper is a brief summary of the development of the mineral deposits in China. Since the foundation of the People's Republic of China, much progress has been achieved in the mineral exploration and exploitation, regional geological mapping, and geological science researches. The authors suggest ...
