The frequency content of strong ground motions from subduction slab earthquakes differs significantly that produced by other categories (tectonic locations: shallow crustal, upper mantle, and interface) in zones. In the last two decades, a large number records events have been obtained Japan. We present ground‐motion prediction equation (GMPE) for this category earthquakes. used dataset reliably identified up to end 2012. GMPEs were based on set simple geometric attenuation functions, site...
The application of high-pressure grinding rolls (HPGR) for ore crushing is considered to be one the effective ways save energy and reduce emissions in processing industry. effect directly determined by forces material during roll crushing. However, mechanical state structure, process parameters, feed particle size, on force needs expanded. Therefore, this paper intends use discrete element method study characteristics materials. Firstly, iron breakage model parameters are calibrated...
The edge effect is caused by poor use of confinement systems, different roll aspect ratios, operating conditions and other factors, which result in uneven pressure distribution between the two crushing rolls along width direction, affecting overall process. To reduce effect, this paper investigates simulation parameter optimisation roll-crushing process ore materials based on discrete element method (DEM). Firstly, parameters iron model are experimentally calibrated, working HPGR simulated...
Leg stretching devices are one of the main instruments used to improve human function. To solve limitations existing leg products, such as single function and low degree coincidence, a device satisfying ergonomics was studied in this paper. Firstly, Box–Behnken Design (BBD) response surface methodology applied establish regression model for force. Secondly, motion analysis conducted on lifting mechanism using analytical methods, data were coupled by Creo Parametric Automatic Dynamic Analysis...
ABSTRACT: Soft soils may pose many challenges to construction of roadway embankments, such as low bearing capacity, excessive settlement, and slope instability. A combined method involving the use deep mixed (DM) columns prefabricated vertical drains (PVDs) was proposed reinforce soft soils. In application method, DM column is usually shorter than PVD. To obtain an analytical solution composite foundation with short long PVDs, drainage system converted into a cylindrical drain wall...
Abstract This study aims at identifying ground‐motion prediction equations (GMPEs) derived from large overseas datasets that may be used for the southwestern part of China (SWC) with or without modifications, source misfits and shedding some light on differences physical parameters among three regions, is, California, Japan, SWC region. To achieve these objectives, correction functions were added to six GMPEs, including two Next Generation Attenuation‐West (NGA‐West) NGA‐West2 a GMPE China,...
The Tianshan orogenesis was initiated as a dynamic response to the subduction of several branches Paleo-Asian Ocean (PAO) and formed significant polymetallic metallogenic belt in western Central Asia. Skarn-related Zn-Pb deposits occupies an essential position mineral resources Tianshan, but its genesis remains ambiguous, economic importance is substantially undervalued. Here, we present comprehensive overview spatiotemporal distribution, geological characteristics, geochemical...
摘要: 东昆仑造山带为古特提斯域重要组成部分,该区古特提斯洋的闭合时间和古特提斯演化相关岩浆岩广泛存在的Nd-Hf解耦原因仍然不清.选取该造山带德龙花岗岩开展锆石年代学和全岩元素-同位素地球化学研究.结果表明德龙花岗岩侵位于中三叠世;岩体属准铝质-弱过铝质高硅I型花岗岩,岩石总体Sr/Y和La/Yb比值较低,与正常岛弧岩浆岩类似;岩体具有富集的Sr-Nd和富集至亏损的锆石Hf同位素特征.综合岩相学、同位素-元素特征表明德龙花岗岩来源于新老地壳混合熔融或者富集地幔和板片(玄武质洋壳和沉积物的混合物)等混合源区来源岩石的重熔作用,这些混合过程导致德龙及同时代中酸性岩浆岩出现Nd-Hf解耦.综合区域地质地球化学特征表明古特提斯洋在240 Ma左右闭合. 关键词: 花岗岩 / 地壳重熔 Nd-Hf解耦 古特提斯洋 洋陆转换 东昆仑造山带 地球化学
ABSTRACT A ground-motion prediction equation for the vertical ground motions from western and southwestern parts of China (referred to as SWC) is presented in this study. Based on Xing Zhao (2021) study, et al. (2017) model ZHAO2017) shallow crustal earthquakes Japan was used reference model. We a bilinear magnitude-scaling function hinged at moment magnitude (Mw) 7.1. The rate events with Mw>7.1 determined by records SWC dataset large Pacific Earthquake Engineering Research Center...
The controlling criterion for differential settlement between the new and old subgrade of widened expressway is an important technical problem concerned by academia engineering field. Based on project, finite element method was used to analyze effects foundation, embankment road surface settlement, in which pavement considered as a whole structure, ultimate tensile strength determine its strength. calculation duration from construction original post road. after bilateral explored. analysis...
ABSTRACTPermian granitoids are widely distributed throughout the northern margin of North China Craton. However, their petrogenesis and related tectonic settings remain highly debated. In this study, we report a granitic complex, i.e., Xiari complex in western segment Bainaimiao arc terrane that is composed granodiorite porphyry, monzogranite, granite porphyry. Zircon U–Pb dating yields an emplacement age range ca. 263–254 Ma. Geochemically, all granites show geochemical features adakitic...

Abstract In the Yili terrane at Awulale mountain, most shoshonitic lavas are related to post-collision extension and were extruded during Late Carboniferous Early Permian (310–280 Ma). Herein, we evaluate a small-volume occurrence of magmas in southern formed c. 346 Ma ago. The high MgO (Mg#) positive Hf isotope values indicate input juvenile mantle-derived material. Still, their Ba–Sr signatures likely inherited from partial melting previously metasomatized lithospheric mantle. We argue...
ABSTRACT This study evaluated the source, path, and site effects of vertical ground motions from western southwestern parts China (referred to as SWC hereafter) using 2403 records 449 earthquakes, including 2008 Mw 7.9 Wenchuan earthquake its aftershocks. Only 677 are 73 mainshocks, 259 events do not have a known focal mechanism. There is large magnitude gap in dataset, for example, there only one event between 6.3 7.8. The average numbers per recording station small, many sites measured...
