北京:城市脉动60年[上]

六十一甲子,弹指一挥间。1949年10月1日,中华人民共和国开国大典,开启了中国历史的新纪元。作为首都——北京这座华美而衰败的古城与共和国一起迎来了一个崭新的时代。六十载城市春秋,六十载风雨历程,让人感慨,更令人思索。新中国成立后,党和政府对首都的城市规划建设工作历来十分重视。作为首都未来发展蓝图的北京城市总体规划,奠基于20世纪50年代初,并经历了复杂多变的发展历程。北京的城     

游戏的人:从游戏广场[1]到“新巴比伦”[2]

荷兰建筑师阿尔多·凡·艾克与艺术家康斯坦特从游戏视角探索艺术与建筑、现实与理想以及理论与实践 之间的对话关联,成为现代主义在荷兰发展中值得关注的重要特点。而正是这种共同理念下的主动交互,恰可成 为我们在凡·艾克诞辰100周年之际,重新进一步审视荷兰建筑发展的重要聚焦和起点。

Guerrillas in the [Urban] Midst: Developing and Using Creative Research Methods—Guerrilla Research Tactics

Abstract

This paper explores what we are calling “Guerrilla Research Tactics” (GRT): research methods that exploit emerging mobile and cloud-based digital technologies. We examine some case studies in the use of this technology to generate research data directly from the physical fabric and the people of the city. We argue that GRT is a new and novel way of engaging public participation in urban, place-based research because it facilitates the co-creation of knowledge, with city inhabitants, “on the fly.” This paper discusses the potential of these new research techniques and what they have to offer researchers operating in the creative disciplines and beyond. This work builds on and extends Gauntlett's “new creative methods” (2007) and contributes to the existing body of literature addressing creative and interactive approaches to data collection.

Discussion on “Impact of orientation of blast initiation on ground vibrations” [J Rock Mech Geotech Eng 15 (2022) 255–261]

Recently, Garai et al. (2022) published a paper on the impact of orientation of blast initiation on ground vibrations. However, some of the claims are not supported by the results of the given tests. In Fig. 1 (see Fig. 8 in Garai et al., 2022), there are contours of measured vibration velocities in 4 directions (every 90°) and an incorrect interpretation between them. By placing all measured vibration velocity values (Gerai et al., 2022) at well-defined points on a single figure, it was not possible to precisely determine the type of vibration velocity, such as radial, tangential and vertical vibration velocities, with their different shapes. An incorrect conclusion was also drawn about the direction of the highest vibration velocity. The paper by Garai et al. (2022) measured the vibrational velocity of the medium through which the seismic wave passed, but used the incorrect term shock wave. The shock wave would have destroyed the seismic measuring instruments. A superposition of the vibrational velocity was considered, but not combined with the vibrational frequency of the seismic wave. This paper presents a method for selecting the time delay between successively initiated explosive charges to the measured frequency of the seismic wave, so that the direction of initiation of the explosive charges does not affect the vibration velocity of the ground through which the seismic wave passes. The theoretical and measured shapes and waveforms of radial velocity and tangential velocity in an opencast lignite mine are then presented. Moreover, the conditions for the formation of shock wave, transition wave and seismic waves are presented.     

Discussion on “Analysis of Bingham fluid radial flow in smooth fractures” [J Rock Mech Geotech Eng 12 (2020) 1112–1118]

Recently, Zou et al. (2020a) published a theoretical analysis on the radial flow of a Bingham fluid, where they argued that the classical analysis by Dai and Bird (1981) violates the mass conservation. The present discussion aims to clarify this conflict between those two studies. It is noted that Zou et al. (2020a) presumed the gap-wise mass flux is negligible in the mass conservation equation, while Dai and Bird (1981) did not require so in their model, and this is found to be the origin of the conflict. In fact, Dai and Bird (1981)’s model is shown to not violate the mass conservation. Therefore, those two models should be viewed as separate models derived from different perspectives. Details of the major difference between the two models are discussed.
