Quaternary stratigraphic regionalization and comprehensive framework in Nanling and adjacent areas
Published 2021-05-01“…The Quaternary sediments in the Nanling and adjacent areas are dominated by alluvial, eluvium and cave deposits, which have lacked of a unified stratigraphic and chronological framework.Based on the results of field survey and research on profiles, the Quaternary strata of Nanling area has been divided into five stratigraphic minor regions: Yongzhou-Chenzhou, Guilin-Hezhou, Shaoguan-Qingyuan, Ganzhou and Daoxian-Yangshan minor region.Meanwhile, the framework of comprehensive strata determined by the lithostratigraphic sequence, biostratigraphy, chronostratigraphic and climatic data has also been established.The results show that the Quaternary System in Nanling area can be compared with the Nihewan Stage, Zhoukoudian Stage, Sarawusu Stage of Pleistocene Series and the unbuilt stage of Holocene Series in China.Its biostratigraphy is characterized by the Gigantopithecus Fauna of Early Pleistocene and the Homo sapiens such as Maba, Daoxian, Liujiang hominin since the late Middle Pleistocene.The climatic stratigraphy are represented by the glacial-interglacial cycle and the local climatic characters in the background of the East Asian monsoon, which were reconstructed by alpine peat and stalagmites deposited from the late Pleistocene.However, the comparison between alluvial and eluvium remains difficult due to the lack of dating data.There is also no detailed comparison between the biological evolution stages and climatic stages.Therefore, the Quaternary stratigraphic research in Nanling should focus on improving the dating precision and establishing a unified time scale in the future in order to promote the refinement of comprehensive stratigraphy comparison.The comparison between continental sediments and marine strata in the South China Sea should be expanded.And it can be used as the basis of applications in hydrological, environmental and engineering geology in Nanling and adjacent areas.…”

Dynamic response charactertstics of long petroleum pipelines extending along mountain ridge under strong earthquake
Published 2021-11-01“…There are many long petroleum pipelines extending along mountain ridges in the mountainous areas of western China.Dynamic responses of the pipelines under strong earthquake have significant effect on their safe service ability.It is necessary for the related investigations to provide guidance for practical construction of the pipeline projects.In terms of a typical section of this kind of oil pipelines at Longmacao village, Yusi, Yunnan, a pipeline-slope 3D numerical simulation model is established considering engineering geology conditions of the slope.Further, dynamic responses of the pipeline including its displacement, axial force, shear force and bending moment as well as overall stability of the pipeline-slope system are computed using FLAC3D program with inputting Wenchuan seismic wave, and the seismic responses at some typical moments such as the moment at peak value of the horizontal acceleration and after the earthquake are specifically obtained.The results show that internal forces of the pipeline reach their maximum values after the earthquake, and the axial force gets high level under strong earthquake but the shear force and bending moment are in small level with about 1% magnitude of the former.Besides, vertical seismic wave has little effect on internal forces of the pipeline, and the position of the maximum internal forces is near the intersection of the pipeline and fault.During strong earthquake, the pipelines appear mainly elastic and plastic deformation in the horizontal and vertical direction, respectively.The accumulated deformation is the major factor to influence internal forces of the pipelines, whose maximum occurs at the moment after the earthquake.…”
