预应力框架梁结构是在框架梁中施加预应力的一种现浇预应力砼结构体系(实属部分预应力结构体系),一般框架柱为非预应力,这种结构具有跨度大、内柱少、降低层高和布置灵活等优点,多用于大跨度工业厂房和公共建筑,而无粘结筋不需预留孔道、穿筋及灌浆等复杂工序,简化了施工程序。 相似文献

公众对公共建筑物的理解往往与专业评价存在一定的差异。专业人士眼中优秀的建筑物,对于公众来说却难以接受。大多数公众是通过媒体、影像资料等间接渠道了解公共建筑物的,却很难与建筑师形成直接交流。是否可能减小这样的理解差异呢?本文对此进行了探讨。 相似文献

The Environment Agency has accepted the need for public participation in decisions concerning river management in keeping with Agenda 21 concerns for environmental policies that command a good measure of public support. In the past, public participation has often relied upon consultations involving formal meetings with interest groups and local politicians. Methods of public consultation are changing. In tapping public opinion the Environment Agency now relies less on public meetings and increasingly more on a direct approach and involvement of the public. Research at Middlesex University is part of the attempt to provide opportunities for the representation of views of the lay public to be considered within the management of rivers and river corridors. The research has used surveys of representative samples of members of the public, often at riverside sites. This paper reports on some of the research projects that have developed on these themes, and analyses the implications of their results for river management and the protection of nature conservation values. 相似文献

公共服务设施是城镇整体生活水平与社会文明程度的代表,同时也是城镇功能的重要组成部分和居民生产、生活中不可缺少的重要物质保障。基本公共服务设施是基本公共服务的空间载体,快速城镇化进程中,随着人民生活水平的不断提高,与公众生活质量息息相关的基本公共服务越来越受到各界关注,基本公共服务设施的相关研究成为焦点,但这些研究多集中于东、中部经济发达地区和人口较密集的区域,而相对于布局松散、规模偏小的内蒙古草原城镇少有涉猎。本文以内蒙古草原城镇为研究对象,探索均等化视角下内蒙古草原城镇基本公共服务设施的适宜性规划布局,为草原城镇基本公共服务设施布局提供借鉴。 相似文献

公共艺术作为城市文化景观中个性鲜明的元素之一,通过自身或泛化于景观场地内的形式介入城市景观空间。公共艺术的形态、材质,不同公共艺术在景观空间内的排布组合都是其在城市文化景观中实现隐喻表达的方式。在城市文化景观里,运用公共艺术的隐喻表达功能,可以凝聚城市的历史记忆,突显场地文化的唯一性,延续城市历史文脉。合理发挥公共艺术的隐喻表达作用,对公共艺术自身"公共性"的回归,城市历史文化的保留与继承,以及公众心灵世界的充实和完善都具有十分重要的意义。 相似文献

Historically, major private companies were the dominant players in urban water supply in France. However, a new era of water supply restructuring is underway, whereby formally private water corporations are being made public. Given that many such public water corporations adopt practices associated with private entities, it is essential to identify what is expected of “public” entities by virtue of the fact that they are public. In this article, we examine the foundational ideas behind the raison d'être of public entities, which engender priorities that differ from their private sector counterparts. Using a research-action methodology, water utility management, staff and consumers of Greater Nantes were asked to specify the meaning of “public” and how it should be operationalized in the case of publicly owned utilities. The research shows that the attainment of public values is what lends legitimacy to a public utility charged with the provision of essential services. In this case, even in a context of neoliberal governance, where private values of an economic nature conflict with public goals; public values take precedence in the management and the regulation of the service. 相似文献

城市公共空间的合理设计已越来越受到社会各界的关注,到底人们需要什么样的公共空间,各地都在为此进行着积极的探索与尝试。文章通过人对城市公共空间的体验,对设计中的城市公共空间的合理性提出疑问,强调了人的行为活动对公共空间设计的要求,强调了人、人的行为活动、活动的场所三位一体的设计思想。通过重庆两个公共空间的分析比较,进一步强调了离开了人的活动、人的故事和精神,公共空间便失去了意义。 相似文献
