Research on Basic Design Education: An International Survey

This paper reports on the results of a survey and qualitative analysis on the teaching of ‘Basic Design’ in schools of design and architecture located in 22 countries. In the context of this research work, Basic Design means the teaching and learning of design fundamentals that may also be commonly referred to as the Principles of Two- and Three-dimensional Design. The body of knowledge associated with Basic Design may be regarded as part of the general theory of teaching and learning design as practiced in many design schools and which has its origins in the classical design schools such as the Bauhaus. In the author’s perception and practice, the pedagogy of Basic Design promotes a holistic, creative and experimental methodology that develops the learning style and cognitive abilities of students with respect to the fundamental principles of design. This includes an understanding of the elements of shape, colour, texture, light, and rhythm in a manner complementary but usually unrelated to the common design methods teaching approach. As is well known among design practitioners, including architects and industrial designers, a deep understanding of the purpose of these fundamental design elements and principles is still relevant to contemporary design practice. The main objective of the research described in this paper was to determine the status and development of Basic Design pedagogy in a significant number of contemporary design schools. On the basis of the results of two surveys conducted in 2001–2002, this paper will identify and illustrate interesting aspects concerning the programmes and organisation of courses delivered by teachers of ‘Basic Design’. This work will also survey the viewpoints of Basic Design teachers in elementary years of design courses and of those teaching design through projects during the subsequent years of the same courses. Interestingly, the design project teachers surveyed in this research expressed a desire to be more involved in the teaching of Basic Design fundamentals which indicates strongly that Basic Design principles are still relevant in contemporary design education terms as they have ever been and that more research is needed in order to better understand and apply the related pedagogy.     

探地雷达在公路改扩建工程检测中的应用

公路改扩建工程在广东省正处于快速发展时期,如何准确得到路面病害情况,是旧路处治方案制定面临的主要问题.依托开阳高速改扩建工程,采用三维探地雷达对旧路进行病害检测,得到道路表面及内部的病害分布情况,并分别与人工徒步调查路况及开挖后内部实际情况进行比对.结果表明:当三维探地雷达检测采样间距设置为2.0 cm、驻波时间设置为0.6 ms、时窗设置为85 ns时,可达到较好的检测精准度;三维探地雷达可实现对路面结构内部不同深度位置的裂缝病害进行探测,精确识别3 mm宽裂缝,并了解裂缝的发展方向及性质.     

北部湾城市群自然资本利用状况、空间分析与驱动因素

以北部湾城市群为例用三维生态足迹模型、偏最小二乘法、空间计量模型分析了其自然资本利用状况、空间相关性、驱动因素。结论:(1)城市群自然资本利用处于不可持续状态;(2)自然资本利用程度划分为低、中、高三类,城市也相应分成三类;(3)自然资本利用的主要驱动因素是人口因素、社会经济;(4)空间分析显示全局莫兰指数为正,空间集聚显著,表明自然资本利用存在空间正相关;空间误差模型拟合度最好,并证明自然资本存量占用与人口总量正相关,与GDP总额负相关。     

基于GIS的边坡三维极限平衡模型研究

自然界中发生的滑坡绝大多数呈三维形态,边坡稳定性分析应从三维的角度进行处理。在实际边坡工程作业中,科学地计算边坡受到边界条件约束、荷载作用、土体性质在空间上变异等实际形态的影响,同样需要进行三维稳定性分析。目前边坡稳定性分析仍以二维极限平衡法为主。当滑动面已经确定时,使用三维分析可以恰当地考虑滑坡的三维形态对安全系数的影响,同时可以避免二维分析时如何选择代表性横截面,计算结果是否合理等问题。     

转向架存放库货架结构设计及有限元分析

为满足转向架检修的需求,在转向架检修库中特别设置一个立体存放库。由于国内目前没有转向架的立体存放库,故采用升降横移式立体车库的方式对转向架存放库货架结构进行了设计。通过有限元方法对货架进行分析与计算,在保证货架承载强度、变形和稳定性的要求下,将原来的壁厚8 mm的钢板改为6 mm,从而减轻了货架的质量,满足了仓储的需要。
