Abstract: The great Wenchuan Ms8.0 earthquake of May 12, 2008 occurred on the central segment of the Longmenshan Fault Belt. Stress was released when the earthquake struck and stress field of seismic source and peripheral areas were affected. Due to the spatial difference in rapture mode and intensity of faul...
Abstract: The study of fault sealing has important reference value and guiding significance for the preservation and evaluation of oil and gas reservoirs and exploration of the distribution of oil and gas. Based on the technologies and methods of FMI imaging logging, focal mechanism solution, field hydraulic ...
Abstract: Taking Jialingjiang formation in Puguang area as an example, with the fractures development law drawn in the area as a basis, the structural curvature method, S-wave wide azimuth anisotropy method and finite element method were used in fracture prediction, and the results and application conditions ...
Abstract: Eastern Himalayan Syntaxis, as one of the fastest uplifting region in Tibetan Plateau, its complex geological environment determines that the engineering geological problems have complexity and particularity and give birth to a variety of geo-hazards. Based on the survey results of the project "Geo-...
Abstract: Taking Shanyang rockslide in Shaanxi province for example, the apparent dip slide characteristics, and creep-buckling failure mode and mechanism of steep stratified oblique rock are analyzed. Based on the beam theory and mechanical model of bending-buckling failure of stratified slab-rent structure ...
Abstract: In order to study dynamic response of anchorage landslide and mechanical behaviors of pressure-type anchor under earthquake, the finite element software ABAQUS was adopted and an anchorage landslide model supported by pressure-type anchor and lattice beam was established. On that basis, the accelera...
Abstract: The gas seepage in compact rock media is different from fluid seepage. The gas slippage effect is an important factor affecting gas flow in compact porous media. This paper summarizes the research progress on the gas slippage effect and synthetically analyzes the production mechanism and conditions ...
Abstract: Based on the landsand-TM remote sensing images, the desertification evolution history of the Hongsibu Basin in the last 30 years is rebuilt. Combining with the 1:50000 geological mapping, the Late Pleistocene sedimentary frame is systematically built and the lithofacies paleogeography for several im...
Abstract: Huangshan Profile in the eastern part of the Northeast Plain is a typical Quaternary profile in Northeast China; however, there are different views on the stratigraphic division and stratigraphic origin of this section. A detailed study on its grain size characteristics is expected to provide furthe...
Abstract: Longhushan area is characterized by late-staged Danxia landforms with Late Cretaceous red beds of Hekou Formation as the scenery layer. Little is known about depositional facies of these redbeds. The outcrop of the Hekou Formation is more than 100 meters thick with abundant sedimentary structures. T...
Abstract: The Chahanchaha granitic body outcrops in the southeast part of the western Tianshan Mountains, Xinjiang, and it is located in the Nalati-Central Tianshan intrusive rock belt at the northern edge of the fault, south margin of the Central Tianshan. The rock type is dominated by granodiorite and monzo...
Abstract: Xinghuadukou Rock Group, as the basement of Ergun massif, its metamorphic age, protolith types and geotectonic setting has always been a hot spot for geologists. With Xinghuadukou Rock Group in lvlin forestry center, north part of Daxing'anling, as the research object, zircons U-Pb isotopic dating w...
Abstract: In order to reveal the whole-theory of fault mechanics, this paper reviews the development of fault mechanics, the due system, the lack of frame and summarizes the differences of academic concerns and research contents. The results show that there are scale differences and target differences in the ...
