沐蓝天碧波 树绿色建筑——访深圳蓝波绿建集团总裁徐宁

我们想让建筑包含更多的东西,流血的、精力耗尽的、让人眩晕的、甚至破碎的;出血的、让人疼痛的、破裂的、有压力的、哭泣的。建筑应该是多孔的、炽热的、光滑的、坚硬的、有棱角的、野蛮的、圆形的、精细的、有色彩的、讨人厌的、贪婪的、做梦般、引诱人的、反叛的、湿的、干的和跳动的。活着或者死的。冷的,就如一块冰一样冷;热的,就如绚烂夺目的翼一样热。建筑必须绚烂夺目。——库珀·希墨尔布劳《建筑必须绚烂夺目》

Environmental Management of Landfill Sites

The paper reviews various options adopted in the UK for engineered protection measures aimed at preventing pollution to the environs of landfill sites. The advantages and limitations of both natural and synthetic lining materials are discussed, recognizing the constraints posed by the geometry and geology of prospective landfill sites. Particular attention is given to the Environmental Safety Centre experience with techniques designed to minimize both leachate and gaseous emissions, and hence prevent pollution of ground and surface waters, and reduce hazards to nearby property. Options for operational practices and restoration procedures are discussed in relation to the control of degradation processes and polluting potential. Included in these options are design and operation of leachate and gas collection/treatment systems, phasing of landfilling operations, and progressive restoration of sites. Monitoring requirements are emphasized as a vital measure of the success or failure of site designs and operational practices in ensuring that appropriate environmental protection is achieved and maintained.     

景框的中介——电影与建筑中的动态布局

本文探讨了作为电影和建筑中的一个主要空间构成主题——景框理念。对空间的电影几何关系和建构几何关系的设置.体块、空间、视角、景观、相机和演员的相对位置和组织等.会产生特殊的张力、关系和动态——所有这一切都指向景框所带来的触媒作用和示能作用。电影与建筑中的空间是许多潜在的力量和相互作用的动力场,它涉及对空间景框、机制和策略的部署与调控,由此实现构成的、语义的和叙事的目的。景框建立了边界,但也促进并提醒可能会遇到的那些模棱两可、针锋相对与制约的突破.以及一种呈现怪诞特征的潜力。     

玻璃钢锚杆托盘及螺母极限应力和位移分析

为了研究支护用锚杆在极限应力作用下力学特性,建立了锚杆托盘及螺母的有限元模型,采用ANSYS程序对螺母及托盘的应力、位移进行了数值仿真分析。研究了托盘及螺母在极限应力下的接触特征;绘制了托盘及螺母的应力云图,得到了托盘及螺母内部的应力、位移分布情况。结果表明,托盘边缘及托盘内部大小圆盘连接位置较为危险;螺母中间位置由于受托盘的挤压容易发生破坏;加肋可以提高锚杆的极限承载力,为结构的优化提供借鉴。     

Designing Whole Landscapes

A whole-landscape approach is critical to ensuring conservation and enhancement of biodiversity in farmed landscapes. Although existing agri-environmental schemes are constrained by property boundaries and voluntary take up, the potential for adopting a whole-landscape approach to planned countryside management is currently favoured by a number of factors. These include economic uncertainty in some agricultural sectors; the introduction of a reformulated rural development policy; increased understanding of relationships between biodiversity and management; and the introduction of Geographical Information Systems (GIS) technology that allows future landscapes to be visualized by stakeholders. Ecological and socio-economic aspects of whole-landscape planning in a study covering 31 neighbouring farms in west Oxfordshire are reported. A baseline was first compiled that included information on: property boundaries; land cover; relationships between hedge and field margin management and key taxa; and farmer socio-economics and attitudes towards agri-environmental measures, conservation and sustainable agriculture. Future scenarios of integrated wholelandscape management were then developed, designed to deliver amenity, environmental and biodiversity benefits. These scenarios were presented and interpreted to farmers and conservation and amenity stakeholders with the aid of GIS-based maps and three-dimensional virtual reality visualizations. Farmers' responses are reported and the potential for implementing whole-landscape planning is discussed .

Magnetoelastische Spannkraftmessung in Bauwerken

Magnetoelastic Measurement of Prestressing Force in Civil Structures The knowledge of the tensile force of prestressing steel elements and its reliable and non‐destructive determination are of essential importance for the assessment of the structural health condition of prestressed concrete structures and tie‐back systems in terms of structural safety, serviceability and durability. For the evaluation of the prestressing force in steel tension members, the measurement technique presented in this contribution is using the magneto‐elastic effect (ME‐effect) of ferromagnetic materials. This effect describes the reverse‐proportional correlation between the mechanical stress and the magnetic properties of ferromagnetic materials. The cylindrical coiled sensors pushed over the tendon and the measuring device developed and practically optimized at the iBMB/MPA of the TU Braunschweig enable a fast and reliable measurement of the prestressing steel force after an initial calibration. In this contribution first the state of the art of prestress measurement techniques for steel tension members is presented. Afterwards, the ME‐measuring method with the basics and merits of magneto‐elastic prestressing force identification is shown. Further recent research results as well as several building applications will be discussed.     

The town and village greens of England and Wales

This paper considers the nature and significance of town and village greens within the landscape of England and Wales. It reflects on problems of definition and on the limited availability of data concerning the origins and geographical distribution of greens. The paper draws attention to the registration of greens following the Commons Registration Act 1965, and summarizes information collated from the registers subsequently prepared by local authorities. Details of numbers of greens and their spatial density at county level are presented, and reference is also made to rights of common on greens, and to the ownership of the greens themselves.     

Pollution due to coir retting and its effect on estuarine flora and fauna

One of the striking features of Kerala state is the continuous chain of lagoons or backwaters existing along the coastal region. The backwaters support rich and diverse life forms and provide crucial nurseries for shrimps and fishes as well as habitat for oysters, clams and mussels which later enrich the ocean and make Kerala the principal exporter of marine products amongst the states of India. The shallow fringes of the backwaters and the channels drawn from them are used for retting of coconut husk. It adversely affects the productivity of the backwaters and is harmful to marine fisheries. The retting of coconut husks in backwaters is brought about by the pectinolytic activity of micro organisms especially bacteria fungi and yeasts degrading the fibre binding materials of the husk and liberating large quantities of organic matter and chemicals into the environment, including pectin, pentosan, tannins, polyphenols, etc. Consequently hydrogen sulphide, phosphate and nitrate contents increase while dissolved oxygen and community diversity of plankton decrease in the ambient waters during the retting process. The present study is to evaluate pollution due to coir retting activity and its influence on quality of water and estuarine flora and fauna.     

我国西南山地城市规划适应性理论研究的一些思考

中国是一个多山的国家,全国2/3的土地、森林、矿产、水能等资源集中于山地。西南地区是人口、民族、资源、地域文化丰富而多样的典型山地区域。国家统筹区域发展和城镇化西部推进战略的实施,西南山地城市（镇）规划与建设显露出理论指导乏力和基础研究薄弱,导致惯性走入“建设性破坏”的误区,造成城乡环境资源、地域文化特色、物质空间形态极大损失。进入新世纪以来,西部地区的城市化发展逐步跃上台阶,“重庆-成都”城市密集的经济发展成为了西部地区重要的经济增长极。创新研究西南山地城市（镇）规划适应性理论与方法,业已成为具有国家高度和重要学术价值的科学问题。论文针对西南山地土地资源稀缺性与生态环境脆弱性的人居建设,城市、建筑空间多维性和自然、人文内涵丰富性的人居环境品质追求,提出指导西南地区城市（镇）规划与建设的适应理论研究目标：山地城镇化适应性理论及发展模式,流域人居环境建设的生态理论及减灾防灾,山地城市（镇）有机更新理论与历史文化遗产保护,山地城市（镇）建设适应性新技术支撑体系。论文拟建立对西南山地城市（镇）规划理论研究的思考并对我国山地城市规划与建设的工作有所指导。
