古建筑木结构的残损点指标是对古建筑木结构进行结构安全评估和加固修缮设计的重要指标,目前主要依据1992年制定的《古建筑木结构维护与加固技术规范》(GB 50165—92)中的规定,为了对该规范中的构架整体性残损点指标进行验证和补充,本研究通过对南方地区传统的穿斗木构体系和抬梁木构体系的典型榫卯节点和构架的试验研究,得出两种木构体系结构的整体性关键残损点指标,并与GB 50165—92规范进行比较分析。结果表明:规范规定的抬梁式木构架和穿斗式木构架的局部倾斜残损点比试验结果小,规范值偏于安全。规范中规定的抬梁式木构架梁柱榫卯连接残损点略小于试验结果,规范值偏于安全;而规范中规定的穿斗式木构架梁柱榫卯连接残损点对于燕尾榫穿斗木构而言是安全的,但对于透榫穿斗木构而言,则是不安全的。 相似文献

清儒补三国地理志成就探析 总被引:1,自引:0,他引:1
胡运宏 《中国历史地理论丛》2009,24(1)
清人补三国地理志者,有洪亮吉、谢钟英、吴增仅三家。总体来说,洪氏草创规模,缺陷最大;谢氏较洪氏有很大改善和进步;吴氏后来居上,成就斐然,且独创前表后考、按时分栏的"地理表"体例。综观三人成果,尽管存在诸多问题,但是基本复原了三国时期的政区情况。 相似文献

北洋政府时期的税制基本上是沿用了清朝后期的旧税制,具有浓厚的殖民地和封建性色彩,阻碍了民族工商业的发展,引起商人的不满与反抗。江苏是民族工商业相对集中的地区,本文以江苏商人为代表,通过考察江苏商人的捐税抗争,说明近代以来中国社会经济发展之艰难,以及民族资产阶级在中国现代社会发展中的地位与作用。 相似文献

The sun, sea and sand model that has characterized the Spanish tourism sector and has caused Spain's tourist sector to become a world-class industry is actually undergoing drastic changes. This model is based on the existence of major tourism destinations characterized by high levels of industry specialisation, which makes them a target of analysis as tourism clusters in which the geographic concentration of synergies reinforces the competitive position. In this study, Spanish tourism clusters are identified using quantitative methods and the current validity of the economies of location that have made them possible are also analysed. Although all the identified clusters can be defined as mature and became less significant during the last decade in Spanish tourism, according to the results the creation of externalities measured in terms of higher generation of profit is higher in companies belonging to the tourism clusters than in those outside of them. 相似文献

This paper puts into question the conventional way of delineating tourism destination borders in terms of taken-for-granted administrative boundaries. Despite the fact that the literature on destination boundaries advocates for conceptual frameworks where customers’ consumption patterns play a more fundamental role, instances of actual attempts of structuring tourism geographies into ‘new tourism areas’ are scant, and instances of zoning on the basis of visitors’ consumption patterns are absent. A method for identifying alternative and more effective consumption-based tourism zones that combines geographical information system and hierarchical cluster analysis techniques, and that relies on time distances between attractions, is thus proposed, and implemented in the case of the Pyrenees mountain region. As a result the region is restructured into nine new tourism zones, which, compared to the original destinations, are more uniform in size and have a higher correlation index between attractiveness and accommodation intensity; they also have different levels of cross-border intensity and are very similar to historical regions; and the more they differ from the original destinations the higher their attractiveness, which supports the effectiveness of the new zoning technique. Four types of tourism zones ranging from higher to lower tourism intensity are also identified. 相似文献

This paper analyses the impact of cultural diversity on cultural policies through an international overview of case studies and reflections. Cultural diversity is generally perceived as a threat toward national cultures. However, this paper argues that (1) there exist substantial national differences in the way in which diversity is perceived and integrated as a policy paradigm; and (2) cultural diversity can be used as an instrument for reconfiguring cultural policies, regardless of the governmental level in question. The authors discuss whether cultural policies of diversity exist and what they are. They also examine the practical consequences of the emergence of a new paradigm concerning the redefinition and implementation of cultural policies within a triple context: the plurality of the territorial configurations of diversity, the simultaneous coexistence of several levels of understanding this issue, and the economic dimensions of cultural diversity. 相似文献
