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

Dor 2001/1 was a Byzantine coaster, about 16.9 m long, with an estimated displacement of 50 tonnes, dated to the first third of the 6th century CE, and loaded with building stones. It was excavated over five seasons, recorded under water, and a section of the shipwreck was retrieved and studied on land. The hull construction was based on frames without any type of planking edge‐fasteners. It is thus among the earliest frame‐based shipwrecks found so far in the Mediterranean. The origin of its construction tradition, with flat frames amidships, hard chine and straight sides, might have been related to a riverine tradition.  相似文献

故宫古建筑内温湿度问题初探   总被引:1,自引:1,他引:0  
博物馆的环境应当相对稳定且有益于文物的保存。故宫博物院作为古建筑博物馆,其特殊性在于古建筑本身也是文物,虽然自身条件较差,但又不能随意改变其外观和结构,导致其保存环境往往不够理想。在研究中论述了故宫古建筑的环境特点,结合在古建筑内文物环境监测和控制方面的若干问题进行有益的探讨,对原状陈列的古建筑温湿度调控的应用效果进行了分析和评估,指出了存在的问题,并提出了对古建筑中环境控制的思考。采用密封性能优良的展柜配合适当的调湿材料可以很好地稳定相对湿度,减少温度变化对相对湿度造成的影响,这是当前国际上文物微环境控制的一个发展方向。  相似文献

The Changsha Street Corps originated in the local militia during the period of the Taiping Rebellion, and it played an important part in Changsha’s urban social management at the grassroots level. However, the role and influence of the street corps underwent changes during the process of modernization and the building of the modern nation–state. By 1920, although the street corps of Changsha still worked as the agent of the state at the grassroots level, its autonomy had been curtailed, and its social influence weakened. In the new social environment, even the maintenance of neighborhood interests became a challenge for the street corps. This article illustrates the readjustments in geopolitical and industrial relations during the process of urban modernization. It also illustrates how a new form of state power, namely the police, infiltrated the social management system, affected the traditional social structure, and complicated the interaction between modern state and society.  相似文献

Abstract: This paper examines an apparent anomaly that lies at the heart of processes of financial exclusion within Britain. Given that the branch networks of banks and building societies have shrunk in size by about one‐third since 1989, a period during which the Government has launched a wide‐ranging set of policies to tackle financial exclusion, why is it that the issue of branch closure has been neutralised as a political issue? After providing evidence to show the extent of branch closure in Britain and illustrating the ways in which geographical research in particular has drawn attention to the nature of this problem, we look at the way the issue of physical access to financial services has been discursively and politically marginalised. We undertake a detailed history of public policy in the area, and the ways in which research funded by industry bodies and Government departments has been used and framed to build a pro‐market, neoliberal policy programme that constructs branch closures as natural and inevitable.  相似文献

京军本为守御京师(畿)而设,但随着政局的稳定和社会经济的发展,皇亲贵戚的生活越来越奢华,京城内的工程修建越来越多,大批京军被抽调借拨到建筑工地,一部分京军竟然演变成职业建筑工人。京军参与修筑的建筑物主要是宫殿庙宇。京军修筑虽然组织方便、节省费用,却严重影响到军队的战斗力,加速了军队的衰败,这也是明朝灭亡的一个重要因素。  相似文献

In this article I argue that the crisis of common collective heritage in Bosnia and Herzegovina is negatively affecting continued peace building processes in the country through an examination of the reconstruction of Sarajevo’s Austro-Hungarian city hall – the Vije?nica. Without a state-level ministry of culture, heritage that attests to a common cultural past uniting the three major ethno-religious groups in the country has suffered immeasurably, especially in comparison to ethnically specific cultural heritage. After the Second World War, the Vije?nica began to embody shared collective memories through its function as the National and University Library of Bosnia and Herzegovina (Nacionalna i Univerzitetska Biblioteka Bosne i Hercegovine). The building’s destruction during the Siege of Sarajevo cemented its place within the Bosnian psyche as a collective memory institution, but its reconstruction is transforming the discourses surrounding the building and the collective memories it embodies. By investigating the reconstruction process and the post-war separation of the National and University Library from the Vije?nica, I show that common collective heritage matters for peace building, and that in Sarajevo, the decay and neglect of such institutions not only mirror the splintering dynamics of ethno-religious nationalism, but also perpetuate them.  相似文献

本文从建筑群基址规模这一概念出发,对文献与考古资料中所体现的中国古代宫殿建筑群做了一个较为系统的探讨,既注意到建筑群基址规模随时代发展而逐渐缩小的趋势,也注意到建筑群基址规模可能是一个规制性的问题,即在大约相近的时代,同等级别的建筑群,如宫殿建筑群,其基址规模也是大体相当的。而同一时期建筑群中,等级较高的,其基址规模也比较大,因而,基址规模是中国古代建筑中一个具有标志性的不可替代的等级符号性建筑要素。从这一概念出发,本文对《周礼·考工记》中的王城规划思想做了分析,得出了更为接近古人记载的王城规划图式,并依据文献史料,发现金中都宫殿、元大都宫殿、明中都宫殿,甚至明南京圜丘坛,都采用了周回9里30步的基址规模尺度,此后的明南京、明清北京又沿袭了明中都宫殿的基址规模。而这一规制可以上溯到宋西京洛阳宫殿、宋汴梁金明池琼林苑,乃至隋唐洛阳宫城、北魏洛阳宫城的基址周回长度和基址面积规模。  相似文献
