The concurrent multiscale method, which couples the discrete element method (DEM) for predicting the local micro‐scale evolution of the soil particle skeleton with the finite element method (FEM) for estimating the remaining macro‐scale continuum deformation, is a versatile tool for modeling the failure process of soil masses. This paper presents the separate edge coupling method, which is degenerated from the generalized bridging domain method and is good at eliminating spurious reflections that are induced by coupling models of different scales, to capture the granular behavior in the domain of interest and to coarsen the mesh to save computational cost in the remaining domain. Cundall non‐viscous damping was used as numerical damping to dissipate the kinetic energy for simulating static failure problems. The proposed coupled DEM–FEM scheme was adopted to model the wave propagation in a 1D steel bar, a soil slope because of the effect of a shallow foundation and a plane‐strain cone penetration test (CPT). The numerical results show that the separate edge coupling method is effective when it is adopted for a problem with Cundall non‐viscous damping; it qualitatively reproduces the failure process of the soil masses and is consistent with the full micro‐scale discrete element model. Stress discontinuity is found in the coupling domain. Copyright © 2017 John Wiley & Sons, Ltd.  相似文献

快速、准确的进行林火火源监测及定位可以有效缩短扑救时间,降低林业资源损失和自然环境污染.为了解决这一问题,采用地理信息系统(geographic information system, GIS)和遥感(remote sensing, RS)作为研究手段、运用实例研究的方法,以MapGIS开发平台为基础,设计并开发“森林防火监测预警系统”.“遥感影像定位”和“视频图像定位”作为两种常用的监测定位手段,可以从宏观和微观的不同角度互补;火险等级预报为监测重点提供参考依据;火势推演分析紧密结合气象信息和植被信息模拟火场扩散情况.结果表明,GIS在森林防火监测定位方面不仅有着良好的可视性,其强大的空间分析特性尤为突出,对促进森林防火管理的信息化、科学化起到十分重要的作用.   相似文献

This paper demonstrates the applicability of cognitive systems or neural networks in predicting the drillibality of rocks and wear factor using engineering properties of rocks. Drillability of rocks is a useful guide for evaluating the suitability of drills for different ground operations. The wear factor of different materials subsequently helps in the selection of proper drills for different drilling operations. Different rocks were tested for Protodyakonov index, impact strength index, shore hardness number, Schmidt hammer number, drillability and micro bit chisels for wear factor. The data obtained from the tests were used to train and test the neural network. Results from the analysis demonstrate that cognitive systems are an effective tool in the prediction and suitability of drilling operations. Application of these predictive models can be a useful tool to obtain the value of these important parameters, they can save time and help to avoid the tedious process of instrumentation.  相似文献

Dissemination of research results is an important part of basic as well as applied research if not the most important one. A large part of research results is published in scientific literature, and since there are many forms of it, the question arises which form is the most visible and attractive to the world scientific community. The International Consortium on Landslides (ICL), based in Kyoto, Japan, is one of the leading institutions in the field of landslide research and landslide risk reduction. On behalf of ICL, Springer Nature has published the journal Landslides: Journal of the International Consortium on Landslides since 2004. It is a very successful scientific journal with regard to its scientometric parameters. Since January 2018, it has been a monthly journal published in full color in electronic as well as printed form. Another form of dissemination of the ICL scientific and professional activities are published books in the form of monographs and proceedings from triennial World Landslide Forums. This paper discusses the impact of 52 books with 3426 chapters taken from the field of landslide science and published by Springer Nature from 2005 to 2018 in the earth sciences category, using different scientometric parameters, such as Bookmetrix downloads and citations, Scopus citations, Scopus h-index, Google citations, and Google h-index. The analysis was performed on the book chapter level (using mainly citations as the main scientometric parameter) as well as on the book level (using book h-index and percentage of cited chapters). Out of the selected 52 titles, 22 were published on behalf of the ICL, with 1419 chapters. The differences among landslide-related books can be quite large; only a few chapters from analyzed book titles were found to be cited frequently compared to highly cited scientific journal articles. On average, the analyzed 3426 book chapters from 52 landslide-related books have been downloaded since publication over 53,000 times each; 1092 chapters (32%) received 2932 citations (2.68 citations per cited chapter and 0.86 citations per published chapter). The analysis shows that the books published on behalf of the ICL are, together with other landslide-related book titles, on the forefront in the Springer eBook collection Earth and Environmental Science (EES). The selected 52 landslide-related book titles are above the average metrics for the whole EES with regard to the total number of downloads per book, the total number of citations per book, and the total number of readers per book. The ICL-related books are getting more downloads but less readers and citations (so far) as the selected non-ICL-related books. A way in raising the visibility and impact of the ICL books on landslide research community would be to support their open access publication in the form of e-Books as much as possible, and inclusion of ICL books into Web of Science.  相似文献

X-ray computed microtomography (µCT) is a promising non-destructive imaging technique based on measurements of the attenuation of X-rays. It provides information on the internal structure of small samples with a maximum resolution of 10 µm. For this study, two porous local natural building stones, the sandstone of Bray and the limestone of Maastricht, were selected. Possible applications of the µCT-technique for qualitative monitoring of changes comprise (1) to non-destructively determine porosity based on 3-D images, (2) to visualise weathering phenomena at the micron-scale, (3) to understand the rationale of weathering processes, (4) to visualise the presence of water repellents and consolidation products, (5) to monitor their protective effects during decay in order to understand the operating mechanisms and (6) to provide advise on the suitability of products for the treatment of a particular rock type. The µCT-technique proves to be a powerful monitoring tool for the future as the combination of 3-D visualisation and 3-D data provide new insights that could optimise conservation and restoration techniques of building materials.  相似文献

A model of the mutual influence of macro- and micro salt diffusion upon migration of model industrial wastes in heterogeneously layered medium (sandy and clayey rocks alternation) is developed. We found that micro salt diffusion into blocks will be minimal, if it occurs under natural conditions. In the case of mutual diffusion and sorption of isotopes as one chemical agent, clayey blocks “shut” due to micro salt diffusion, and radionuclides do not penetrate into them.  相似文献
