2013, 19(3): 225-241.
Abstract (544) HTML (214) PDF (1138KB)(40)
Abstract:
Earthquake induced landslide is one of the most common geological disasters in great earthquake of continent internal mountain. It not only has large amount and great scale, but also causes serious damage for human activities. So, it is extraordinarily significant to analysis the earthquake induced ...
OVERVIEW OF QUATERNARY DATING METHODS AND THEIR APPLICATION IN NEOTECTONICS AND ACTIVE TECTONICS RESEARCH

Abstract (573) HTML (108) PDF (1824KB)(83)
Abstract:
The quantitative or semi-quantitative research of neotectonics and active tectonics largely relies on the establishment of stratigraphic sequence and the time scale, how to obtain relatively precise the stratigraphic ages and the age of occurrence of geological events is the key factor to determine ...
ACORITE U-Pb CHRONOLOGY CHARACTERISTICS AND ITS GEOLOGICAL SIGNIFICANCE OF DUCTILE SHEAR DEFORMABLE BELT IN SOUTHEASTERN HAINAN ISLAND, CHINA
LI Sun-xiong, WEI Chang-xin, WANG Yan-hua, CHEN Fang-ying
2013, 19(3): 267-274.
Abstract (256) HTML (117) PDF (1593KB)(11)
Abstract:
The ductile shear belt exposures in Mangsan Reservoir-Diaoluoshan Tree Farm-Xinglong area successively with its strike being north-east. The lithology is tectonic gneiss and granite of mylonitization, and main minerals are composed of feldspar, quartz and biotite. The rock develops as "S-C" fabric, ...
MICROTECTONIC FEATURES AND EVOLUTION OF THE YUSHIGOU PERIDOTITE ROCK FROM THE QILIANSHAN MOUNTAIN
YANG Yan, YANG Bo, ZHANG Hong-yuan
2013, 19(3): 275-286.
Abstract (202) HTML (368) PDF (2069KB)(9)
Abstract:
As a main component of upper mantle, peridotite affects the rheological behavior of the upper mantle. The microstructures contain records of tectonic events experienced during the development process of the specimen. Rheological parameters, such as temperature, confining pressure, factors of water a...
A PRELIMINARY DISCUSSION ON FEASIBILITY USING THERMALLY TRANSFERRED OPTICALLY STIMULATED LUMINESCENCE (TT-OSL) METHOD TO DATE THE FINE-GRAIN QUARTZ EXTRACTED FROM GANZI LOESS
ZHANG Ke-qi
2013, 19(3): 287-294.
Abstract (279) HTML (119) PDF (1371KB)(10)
Abstract:
This paper attempts to date the loess from Ganzi area, Sichuan province, using a new method-TT-OSL protocol for OSL dating. A preliminary experimental study was conducted loess from the Ganzi-A section. Testing result showed that the naturally recuperated OSL signal intensity increases with depth of...
APPLICATION OF GIS IN LANDSLIDE STABILITY EVALUATION: A CASE STUDY FOR ERMANSHAN LANDSLIDE
TAN Chun-hong, ZHU Zhi-ming, ZHOU Kai-rui, BIAN Jing-sheng, WEI Yuan, ZOU Zu-yin, ZHANG Yun-qi
2013, 19(3): 295-303.
Abstract (174) HTML (115) PDF (1762KB)(14)
Abstract:
In this paper, the method of theoretical knowledge, field surveys and laboratory experiments were used to analyze the environmental conditions, development characteristics and mechanism of the Ermanshan landslide in Hanyuan County, selecting the characters of landslide, geological structure, elevati...
APPLICATION OF 90°-PHASE SEISMIC DATA IN PREDICTION OF SANDSTONE
PAN Wei-hong, LIU Hao, ZHANG Liang, ZHANG Shuai, ZHAO Chun-chen
2013, 19(3): 304-314.
Abstract (245) HTML (180) PDF (2197KB)(29)
Abstract:
Taking the 2nd Member of Shahejie Formation in the Yellow River Mouth sag as an example, geological models were built depending on the 90° phasing of seismic data and the geologic setting. The modeling synthesis records from 0°-phase to 90°-phase were used to make the geological models more precise....
A FIBRE OPTIC EXTRINSIC FABRY-PEROT INTERFEROMETER WITH TEMPERATURE COMPENSATION FOR FAULT MEASUREMENT
PENG Hua, MA Xiu-min, WANG Zhen, CUI Liu-zhu, JIANG Yi
2013, 19(3): 315-324.
Abstract (248) HTML (93) PDF (1697KB)(7)
Abstract:
Fibre optic EFPI sensor is usually very small in size while the fault size is relatively big, so it is not suitable to be installed at the fault for the fibre optic EFPI. As a result, fibre optic extrinsic Fabry-Perot interferometer for fault measurement, EFPI was present. EFPI structure is formed a...
CONTACT ALGORITHM OF 3D MECHANICAL FINITE ELEMENT MODELING FOR SEPARATION OF OVERBURDEN LAYERS AND ITS APPLICATION
WU Ze-dong, Xue Ai-min, Cao Ding-tao
2013, 19(3): 325-333.
Abstract (250) HTML (141) PDF (1828KB)(7)
Abstract:
Based on the specialty of separation layer, this paper proposes a new contact algorithm with the adoption of massive parallel computation for the study of separation of overburden layers in coal mine production. We have done the real 3D mechanic simulation and get the potential location, shape and v...
COMPLEX FLAC3D THREE DIMENSIONAL GEOLOGICAL MODELING BASED ON MOVING LEAST SQUARES METHOD
LI Guo-qing, Wang Xin-qing, YIN Gai-mei
2013, 19(3): 334-342.
Abstract (240) HTML (119) PDF (1741KB)(8)
Abstract:
FLAC3D is an excellent computer code for rock-soil mechanics numerical simulation, but it performs poor in modeling complex geological body.
