The Imperial Citadel of Thang Long is a crucial case in ancient Vietnam’s planning and design history. Although historical materials indicate that the orientation of the Imperial Citadel of Thang Long has a dialectical unity relationship with the surroundingmountains, current research is only speculative generalization and lacks empirical analysis. Based on existing findings, this paper identifies the collineation measurement as a generalmethod in the Sinosphere countries for determining spatial orientation. Using a mixed-method of historical archives, fieldwork and simulation model, this paper summarizeshistorical cluesandthreedesignperspectives related to spatial orientation by statistical analysis. Further, it analyzes the logic and application of collineation measurement in constructing the Imperial Citadel of Thang Long. The results show that Vietnamese designers used Tàn Viên Mountain as a component of Thang Long city by collineating the twomountain peaks to the west. Tàn Viên Mountain and the highlands extending eastward fromit are used as the key to establishing the position of the Imperial Citadel, setting the spatial structure of human settlements, and the development of city space. The location, layout, and formof important buildings in the Imperial Citadel are also closely related to the surrounding landscape within 50 km. 相似文献

Xavier Kurten (?–1840) was a Prussian landscape gardener who worked for the Savoy family in the Piedmont region of Italy in the first half of the nineteenth century. He designed or redesigned all royal parks, creating a specific style based on the English naturalistic garden approach. This research was performed with the aim of investigating the development of the English landscape garden in Italy. Historical documents relating to Kurten’s biography and his work in Piedmont, including plans, were collected and analysed. We analyse and discuss the features that characterised his work: the relationship between the landscape—garden—house, the path system, the use of water, the vegetation, and the garden as a productive landscape. Kurten’s style is compared with the projects of William Kent and Lancelot ‘Capability’ Brown. 相似文献

The First World War (WWI) had a notable influence on the landscape at the former Western Front in Belgium. Research on a landscape scale is necessary to understand the destructive and constructive impact of the war and its consequences for the post-war landscape in a holistic manner. This paper focuses on the trajectory and impact analysis of three study areas with contrasting landscape types and aims to indicate possible preserved military relics today. Therefore, landscape changes are studied using historical aerial photographs (WWI and WWII) and contemporary orthophotos. A military landscape characterisation is made based on land use/land cover and linear structures that were mapped throughout time. Specific landscape trajectories could be designated as areas with a possible preservation of WWI heritage, with a related impact degree. The results are useful for sustainable heritage management and for further interdisciplinary research on WWI-heritage, by providing a broad knowledge of the area. 相似文献

The response of a jointed pipeline to tunnelling-induced ground settlement relies largely on the soil-pipe interaction. An analytical solution incorporating the Pasternak model is formulated here to estimate a jointed pipeline's deflection and bending moment. Subsequently, a procedure is proposed to transform the jointed pipeline to an equivalent continuous structure for a deflection evaluation. Case studies are conducted to verify the analytical solution, followed by parametric studies to assess the effects of the Pasternak model's parameters and the pipe joints. The analytical solution is validated by the experimental results in the literature. The parametric studies show that the number and distribution of the joints have a mild effect on the pipe deflection, whereas their influence on the pipe bending moment is significant. Similarly, the pipe bending moment is more sensitive than the pipe deflection to subgrade shear stiffness. 相似文献

地铁建设的快速发展对于缓解国内大中城市的交通拥堵问题具有极其重要的意义,然而,轨道交通运营线路多通过城市的主要街区以及繁华商圈,车站周边地表受基坑开挖影响产生沉降等环境问题较为显著,须在支护设计阶段对其进行有效地预测及控制,以便最大程度地降低施工阶段发生工程灾害的机率。基于厦门地铁1号线车站建设过程中邻域地表沉降的监测数据,对实测沉降槽曲线进行归一化处理和统计分析,得出适用于厦门地区类似工程条件下地铁车站基坑施工诱发周边地表沉降的经验预测方法,为后续的地铁建设提供参考建议。 相似文献

软土地区基坑开挖引起的变形具有明显的空间效应,为了进一步研究开挖引起周边地面及建构筑物变形的特性,结合对温州某大型深基坑工程的监测,从垂直于基坑围护墙以及平行于围护墙两个方向,对基坑外地面道路以及建筑物的沉降和裂缝情况进行了监测分析,总结了开挖引起基坑外地表沉降的分布特性,分析发现:基坑边角对围护墙变形以及地表沉降具有明显限制作用;在垂直于基坑方向上,处在沉降主要影响区2He范围内,建筑物均具有明显的差异沉降,最大角变量达到1/1300;平行基坑方向距离边角(0.4~1.2)He(最大开挖深度)范围观测到纵向裂缝,沉降变化率较大,可能破坏道路或建构筑物;此外,桩基础的建筑物总沉降以及差异沉降均明显小于条形基础建筑。 相似文献
