地下综合管廊基坑支护方案经济评价及优化探讨

目前城市地下综合管廊通常采用明挖基坑进行施工.城市地下综合管廊由于结构体量大,整体埋深较深,因此基坑支护费用较高,有的地下综合管廊基坑支护费用甚至超过管廊主体结构费用.在综合管廊主体结构规模确定的情况下,管廊基坑支护方案的选择往往决定了综合管廊整体工程造价的高低,因此控制综合管廊基坑支护的造价是控制综合管廊整体造价的重...     

铁路隧道辅助导坑与正洞交叉处三角区施工技术

随着铁路建设的发展,长大山岭隧道在铁路建设中的比例越来越大,铁路建设中的长大隧道往往采用增设辅助导坑的方法以减小施工难度,加快施工进度,因此辅助导坑与正洞交叉处三角区的处理成为长大隧道施工中不可避免的课题,文章介绍了拉日铁路色麦村隧道辅助坑道与正洞交叉口三角区施工技术,为以后的类似工程提供设计和施工经验参考。

Local contexts as activation mechanisms of market development: contemporary art in emerging markets

The paper studies how local contexts contribute to the emergence of markets. In particular, it explains how potential entrepreneurs are motivated to become active in establishing new markets. Empirically, the focus is on contemporary art markets in two emerging countries: India and Russia. The paper draws upon qualitative interviews with 65 contemporary art dealers conducted in New Delhi, Mumbai, Moscow and Saint Petersburg. We show how different socio-cultural contexts function as activation mechanisms: in India, family backgrounds predominantly structure the decision-making processes, among others through the economic, social and cultural capital which these families provide. In Russia, by contrast, such family background is non-existent. Instead, the socio-economic turmoil of 1990s and 2000s as well as the strong involvement of the state function as activation mechanisms. We suggest that these different activation mechanisms contribute to explaining the diverging market performance in both countries.     

浅谈地下综合管廊PPP项目实施关键点与运营管理

在进行市政基础建设的过程中,地下综合管廊建设是其中的关键点。为了缓解当前建设的财政压力,引入PPP项目是非常重要的。这种运营管理模式下,政府和社会资本共同合作,能够满足城市建设对于资金的需求。论文将针对PPP项目实施的关键点以及运营管理的具体情况进行分析,并提出一定的建议。     

基于ABAQUS的变电站GIL管廊基坑边坡稳定性分析

气体绝缘金属封闭输电线路综合管廊工程(gas-insulated rnetal-enclosed transmission lines, GIL管廊)以其安全、可靠的优势,广泛应用于城市变电站建设。GIL管廊安全施工的前提是保证开挖基坑边坡稳定。基于Mohr-Coulomb强度准则,采用ABAQUS模拟上软下硬地层GIL管廊土方开挖边坡地层变形情况,利用地应力平衡法和强度折减法确定边坡安全系数,验证工程支护方案的合理性,进而分析边坡失稳机理,为边坡地层变形预测、支护方案确定提供参考。结果表明,ABAQUS可以有效模拟强度折减;加固后边坡的最大位移减小60.5%,地面沉降不再出现,安全系数由原来的0.987提高至1.527,增大54.7%;上软下硬地层边坡开挖时,上部软弱土层形成按地层分布的多个潜在滑移面,下部岩层会以楔形体滑移模式对坡脚形成挤压作用。     

BIM+GIS在城市综合管廊监控报警与运维管控系统中的应用

本文提出了一种城市综合管廊监控与报警集成管控平台的架构,并对以BIM+GIS为核心的系统功能进行了研究和分析,通过GIS实现对管廊整体及设备设施的全局定位及管理,利用BIM实现对管廊设备的空间精准定位,二者相互融合,创造性的提出了多种基于BIM\GIS集成的功能应用,全面实现对综合管廊设备设施的可视化管控,大大提升了综...     

业主BIM在综合管廊中的应用研究

Extending the theory of metaphor in marketing: The case of the art gallery

Abstract

This study analyses the metaphor of spirituality in the non-profit art gallery, a metaphor overlooked in previous marketing research. Using content analysis and interviews in a single depth case study, this article illustrates how spirituality has been a staple in the non-profit art gallery over time. It was found that even though the non-profit art gallery acknowledges its use of spirituality, it has a paradoxical attitude to it. Therefore this article (a) traces the historical influences that led to the extension of metaphor in the art gallery and its relationship to marketing theory, and (b) draws on Hunt and Menon (1995 Hunt, S.D. and Menon, A. 1995. Metaphors and competitive advantage: Evaluating the use of metaphors in theories of competitive strategy. Journal of Business Research, 33(2): 81–90. [Crossref], [Web of Science ®] , [Google Scholar]) to identify deliberate and emergent strategies using metaphor in the non-profit cultural organisation.
