本文通过对向阳隧道和八一隧道分别采用传统矿山法和新奥法进行数值模拟,计算结果表明,由于传统矿山法和新奥法的理念不同,用传统矿山法设计施工,造成二次衬砌局部应力集中,二次衬砌应力较新奥法大,由此证明新奥法是目前较合理的隧道工程设计施工理念。  相似文献

As the legal framework is designed for an established energy regime, innovative solutions for the energy transition often encounter barriers. Since rapid changes in the legal framework may involve uncertainties, testing solutions in the exceptional framework of regulatory sandboxes can be a constructive instrument of innovation policy. Until June 2021, Austrian energy law contains neither an explicit authorisation to grant such exemptions nor custom-made regulatory sandboxes. This paper is the first to investigate the practical need for regulatory sandboxes in Austria (specific fields of experimentation were identified) and elaborate necessary changes for energy law eligibility, taking European law into account.  相似文献

隧道锚在实际工程中应用不多,目前对其稳定性的研究相对较少。基于大型通用非线性有限元分析软件ABAQUS的计算平台,利用该软件提供的用户材料子程序UMAT接口,将基于Rankine准则的Mohr-Coulomb模型添入ABAQUS中,采用Foamn语言开发了接口程序,并在此基础上对四渡河悬索桥隧道锚进行二维弹塑性有限元分析,计算了初始地应力场,模拟了隧道锚与公路隧道的新奥法施工过程,并考虑了开挖过程中隧洞周边接触软弱层的形成。将锚碇围岩的稳定性和锚固系统的整体安全度作为主要研究内容,其计算结果和长江科学院采用FLAC3D的分析结果比较,二者具有一致性。研究结果表明,所研制的接口程序开发思路正确,计算精度满足要求,所完成的工作为隧道锚设计提供了依据,具有相当重要的工程价值。  相似文献

Besides technical parameters, consumer behavior is the most important issue with respect to energy consumption in households. In this paper, the results of a cross-section analysis of Austrian households are presented. The impact of the following parameters on residential energy demand for space heating have been investigated: (i) thermal quality of buildings; (ii) consumer behavior; (iii) heating degree days; (iv) building type (singleor multi-family dwellings). The result of this investigation provides evidence of a rebound-effect of about 15 to 30% due to building retrofit. This leads to the conclusion that energy savings achieved in practice (and straightforward the reduction in CO2 emissions) due to energy conservation measures will be lower than those calculated in engineering conservation studies. Straightforward, the most important conclusions for energy policy makers are: (i) Standards, building codes, respectively, are important tools to increase the thermal quality of new buildings; and (ii) Due to prevailing low energy prices, a triggering tool has to be implemented which may be rebates or loans.  相似文献

The building sector is one of the highest energy consumers in Austria. The potential to save energy in existing buildings is very high. Current Austrian policy incentives encourage home owners to renovate buildings to meet the European requirements, reduce energy consumption, and reduce CO2 emissions. Nevertheless, there are often discrepancies between the measured and calculated energy consumption results despite efforts to take parameters into account such as the exact geometry and thermal properties of the building, energy demand for hot water, heating, cooling, ventilation systems, and lighting in the planning phase for selecting the best reconstruction option. To find the answer to this problem, many buildings are carefully investigated with the help of measurements, interviews, and simulations. This paper presents the analysis and results of the investigation of the impact of lifestyle on the energy demand of a single family house. The impact on energy performance of the most important parameters was observed by systematically changing parameters such as changing from a decentralized to a centralized heating system, considering various technologies and fuels for producing electricity and heat, use of renewable energy sources. Different occupant behaviours were changed systematically. The effects of these measures are analysed with respect to primary energy use, CO2 emissions and energy costs. The results of these investigations show that the lifestyle and occupants’ living standard is mainly responsible for the differences between the calculated and measured energy consumption.  相似文献

The aim of this research note is two-fold, firstly, to clarify the growing interaction between regional science and Austrian economics and their awareness of each other. We elucidate the Austrian methodology, called praxeology, which is especially misunderstood in regional science. Secondly, we tentatively sketch a possible contribution of Austrian economics to regional science. The core of the new economic geography is the idea of external economies of scale. Agglomeration of firms often leads to lower costs of existing products, and is a stimulating environment for the invention of new products and the development of new ideas. Austrian economics, which places discovery at the centre of its analysis of the market process, should be able to explain why (public) regional investments may be unsuccessful and why they can be successful.Received: 2 February 2002, Accepted: 25 June 2003, JEL Classification: B41, B53, R12  相似文献

奥地利建筑师约翰·伯恩哈德费舍尔冯埃尔拉赫(Johann Bernhard Fischer von Erlach,1656-1723)是欧洲巴洛克时期哈布斯堡王朝(Habsburg Monarchy)的重要建筑师之一。令人感兴趣的是他的一些设计作品表现出与中国之间的明显联系。同时他也是欧洲最早公开出版的世界建筑史图册《历史性建筑的设计》(A Planof Civil and Historical Architecture,1721)的作者,此书第一次将中国和泰国作为世界建筑的一部分进行比较研究。本文介绍此位奥地利建筑师的生平和工作,并分析他和中国以及中国式风格建筑的关系。文章第一部分从西方建筑传统的大背景下讨论费舍尔的建筑成就。第二部分,研究在欧洲中国风背景下他的建筑活动,并介绍奥地利中国式建筑风格体系的构成。  相似文献

新奥法是一种被广泛应用的隧道施工方法,也是一套完整科学的思想体系。新奥法遵循自然规律,以实际情况为依据,与道家学说的无为而治在思想上有着高度的相通性。无为思想同时对工程建设与灾害治理等都具有良好的启示,工程师应该从中国传统哲学中获取有益的启示,以都江堰水利工程为典范,在工程建设和灾害治理中能够尊重自然,正确应用自然规律,逐步实现人类工程活动的可持续发展,达到人与自然和谐发展的目标。  相似文献

Static Analysis and Verification of Steel Fibre Reinforced Concrete Foundation Slabs according to the Austrian Guideline “Fibre reinforced concrete” and DBV (German Concrete Association) Recommendations “Steel fibre reinforced concrete” Steel fibre reinforced concrete is used for foundation slabs of housing structures since many years. The Austrian guideline [1] and the DBV recommendations [2] provide material properties and design values for calculation and verification of steel fibre reinforced concrete structural members. This paper provides a comparative study on foundation slabs taking both guidelines into account. A nonlinear finite element parameter study has been performed in order to verify a simplified static calculation and verification method. This calculation method is based on the yield line theory. This paper concludes with a sample calculation for steel fibre reinforced foundation slabs according to the Austrian and German design recommendations.  相似文献
