NUMERICAL MODELING FOR WENCHUAN EARTHQUAKE MECHANISM
WANG Lian-jie, CUI Jun-wen, ZHOU Chun-jing, SUN Dong-sheng, WANG Wei, TANG Zhe-min, QIAN Hua-shan
2009, 15(2): 105-113.
Abstract (220) HTML (109) PDF (850KB)(14)
Abstract:
In this paper, strain softening model is used for modeling the Wenchuan earthquake.Results shows that this earthquake was caused by compressing of Qinghai-Tibet Plateau and block of Sichuan Basin.The stress drop, energy release amount, the magnitude of dislocation of fault, coseismic displacement, d...
STABILITY AND STRESS MEASUREMENT NEAR THE QINGCHUAN FAULT IN THE NORTHERN LONGMEN MOUNTAINS
PENG Hua, MA Xiu-min, JIANG Jing-jie
2009, 15(2): 114-130.
Abstract (273) HTML (119) PDF (3932KB)(22)
Abstract:
After the M8.0 Wenchuan earthquake, it becomes an important concern that whether aftershocks direct to Hanzhong along the Qingchuan fault and a strong aftershock also occur.The study on in situ stress measurements was carried out at Ningqiang region in the northeastern section of the fault in order ...
COUPLING BETWEEN ENDOGENIC AND EXOGENIC GEOLOGICAL PROCESSES IN THE WENCHUAN EARTHQUAKE AND EXAMPLE ANALYSIS OF GEO-HAZARDS
ZHANG Yong-shuang, SHI Ju-shong, SUN Ping, YAO Xin
2009, 15(2): 131-141.
Abstract (348) HTML (247) PDF (3337KB)(26)
Abstract:
The endogenic and exogenic geological processes are two indispensable processes for geo-hazard occurrence.However, only was exogenic geological process widely emphasized in the past, while the coupling between endogenic and exogenic geological processes were only presented in formations of experient...
A CONSIDERATION ON REGIONAL CRUSTAL STABILITY ASSESSMENT AFTER MS8.0 WENCHUAN STRONG EARTHQUAKE IN CHINA
TAN Cheng-xuan, SUN Ye, WU Shu-ren, HAN Jin-liang, WU Fang, SUN Wei-feng
2009, 15(2): 142-150.
Abstract (209) HTML (129) PDF (1269KB)(10)
Abstract:
A new consideration and knowledge on regional crustal stability assessment was awoken by the MS8. 0 Wenchuan earthquake in China. This paper thoroughly introduces the basic theories of regional crustal stability assessment in China, including 'safety island' theory, geological texture control theory...
CO-SEISMIC DEFORMATION OF "5.12" WENCHUAN EARTHQUAKE BASED ON D-INSAR
YAO Xin, ZHANG Yong-shuang
2009, 15(2): 151-161.
Abstract (306) HTML (169) PDF (3587KB)(6)
Abstract:
Co-seismic deformation is important original information to determine seismogenic faults, to understand mechanism of earthquake, to analyze fault movement, to evaluate the earthquake property lo sses as well as to discover the trend of future earthquakes. However, ways to survey co-seismic deformati...
TECTONIC DEFORMATION FEATURES OF SHENNONGJIA REGION IN EASTERN DABASHAN FORELAND STRUCTURAL BELT
LI Jian-hua, ZHANG Yue-qiao, SHI Wei, LI Hai-long, DONG Shu-wen
2009, 15(2): 162-177.
Abstract (237) HTML (118) PDF (5475KB)(10)
Abstract:
Shennongjia is located in the eastern part of Dabashan foreland arc-shaped structural belt. With the Yangri fault as a boundary, this region can be divided into the northern and southern parts. The northern part is characterized by W-E trending basement-involved detachment and cover folding, with th...
STRUCTURAL FEATURES AND TECTONIC EVOLUTION OF THE WEI-ZI-LUO FAULT ZONE IN SOUTHWESTERN GUIZHOU PROVINCE
ZHANG Rong-qiang, ZHOU Yan, WANG Xin-wei, LI Shuang-jian, LI Song
2009, 15(2): 178-189.
Abstract (383) HTML (137) PDF (3527KB)(39)
Abstract:
The Wei-Zi-Luo fault develops in southwestern margin of the Yangtze block. This is a deep crustal fault zone and controls the deposition and deformation styles of the region. Based on detailed field observations, fluid inclusion analysis and temperature measurements, and using cross section balance,...
CHARACTERISTICS OF FAULTS IN THE PU-WEI RING DEPRESSION AND ITS CONTRIBUTION TO MIGRATION AND ACCUMULATION OF OIL AND GAS
LIU Wei, YU Chuan-mou
2009, 15(2): 190-200.
Abstract (227) HTML (155) PDF (1701KB)(5)
Abstract:
The Pu-Wei ring depression, with complex structures, has been poorly studied. Based on analysis on the faults, this paper deals with function of the faults in migration and accumulation of oil and gas. The research demonstrates that both the Pucheng-Chenying fault zone and the Weidong-Wendong fault ...
STUDY ON THE TECHNOLOGY AND METHOD OF 3D GEOLOGICAL MODELING: A CASE STUDY OF THE EAST KUNLUN OROGENIC BELT
ZHANG Si-ke, NI Jin-yu, GAO Wan-li, HU Dao-gong
2009, 15(2): 201-208.
Abstract (273) HTML (264) PDF (1714KB)(14)
Abstract:
The key technology of 3D geological modeling is how to make use of professional GIS platform, which can truly get the reappearance of 3D geological entities and spatial analysis, to provide technical support of geological research and exploration of mineral resources. In this paper, taking the east ...
