The paper describes some recent developments in the application of lower bound shakedown analysis to geotechnical problems. The theoretical basis of shakedown analysis is briefly reviewed along with the necessary finite element and optimization procedures. In terms of applications, the primary focus is on pavement design which is discussed in some detail.
Ground penetrating radar (GPR) method is a non-destructive geophysical method that is used to detect subsurface heterogeneities and also recognition of various shallow targets. In present research, forward and inverse modeling of GPR data applied for archeological study has been made. The study area is Tappeh Hissar, Damghan, in which GPR data along several survey lines have been acquired using...
岩土工程破坏以及灾害往往伴随着大变形问题。近年来, 随着计算机技术的快速发展, 大变形数值模拟方法在岩土工程领域有了广泛应用, 例如利用物质点法(MPM)或者光滑粒子流体动力学法(SPH)模拟边坡垮塌、软土地基中的基础沉降或失稳, 利用耦合拉格朗日-欧拉法(CEL)分析隧道破坏对临近地下结构物的影响等。为此, 本专辑收集了在该研究领域具有代表性的研究成果, 介绍了岩土工程大变形模拟技术的进展和未来发展潜力, 希望能帮助读者快速了解其应用现状, 并为岩土工程的数字化发展提供科学依据和技术支撑。
The Ontology for Biomedical Investigations (OBI), written in OWL DL, is being developed by a large consortium seeking to provide a crossdomain, shared framework for representing investigations in the biological and biomedical sciences. In this paper we report our experiences and describe our development process as it pertains to OWL, which includes a number of elements that might inform tool de...
