怀念

我和《规划师》的接触,从20世纪90年代末大学毕业就开始了。那时,其实只有城市规划背景的自己却很幸运地进入了广西区公安厅工作,成为了一个“交通管理工程师”,负责交通秩序管理、交通缓堵、停车场规范等工作。由于工作关系,我接触了许多不一定是“城市规划”背景却与城市规划有着千丝万缕联系的实践。他们的想法,他们的见地和他们的抱负,让刚从规划院校毕业的我醍醐灌顶、受益匪浅。从前,我只是从书本上得知,规划目标的多元性、规划专业的跨学科性,     

永远的怀念

1950年夏．我在上海参加高考，分别报考了原中央大学(现为东南大学)和清华大学的建筑系，有幸都被录取了。中央大学是我国最早创立建筑系的高等学府，有我的好几个同学考取该校，离家又近，但我还是选择了清华，当然是因为慕梁思成先生的大名。到达清华报到后又听说梁先生的夫人是林徽因先生．而且也在系任教。真是喜出望外，     

深深的怀念

中国工程院资深院士、国际著名混凝土专家吴中伟教授离开我们已经五年了，这位老领导、老师长永远活在我们心里。     

地名的怀念

我住在北京北边的一个地方。但是如果把我周围的地名说出来，就好像生活在联合国总部。我的西边有一个别墅区——“雪梨澳乡”，悉尼还不够，还要加上澳乡：我住处的南边有一处新开盘的楼盘，名为“美伦堡”，不知为什么，每经过此处，我都会想起“纽伦堡审判”：我的北边，有一个住宅区，名字叫“北岸布鲁斯”，好像是铜管乐队的名字：我的东边有一幢大楼叫“第五大道”。     

永远的怀念

每年的清明,中国人普遍给老祖先或亲人、朋友上坟,扫扫墓碑,添把新土,或敬献花圈、花篮,以慰藉长眠者。 今年清明节一到,邝家寨上坟的人群纷纷涌向一处坟茔。这里长眠着一对年轻的夫妻。 去年冬春之交,人们闲遐无事,一伙老头儿聚集在邝三爷家的打麦场内,背靠着麦草摞儿,     

永远的怀念

一代宗师,德高望重的园艺植物学家,著名的教育家——陈俊愉先生走完了光辉的一生,安详地离我们而去了。我心中感到无尽的悲伤和无穷的思念。就在他辞世前不久,我还和他通了电话互致问候,他的声音和往常一样洪亮,他的笑声也是爽朗依旧。他很高兴地告诉我,他最后的2本书稿已经完成,并交给出版社了,出版费也已落实,很高兴能完成这件     

永恒的怀念

辛巳年夏,乌云密布,雷雨阵阵.余独临南窗,强扶病体,整理君之遗诗.墨迹犹存,而人已不归,不禁凄然. 呜呼!君远行之初,余肝肠寸断,终日以泪洗面,神志恍惚,不知昼夜,每疑为梦.盼梦醒而君坐于床沿,问何睡之久也.然非梦也,真也!君己弃吾而独自归去,令余跌入伤悲之深渊.今君不归已近二年矣,伤悲之心未能稍减.漫漫岁月,如何度此凄怆之风烛残年?伤哉,夫君何忍也.     

深切的怀念

天增同志走了,走得如此匆忙,连一句嘱咐的话都没留下,怎能不让人悲痛与怀念。天增同志是一九六二年清华大学毕业后分配到华东建筑设计院与我共事的。他做的第一个项目就是住宅竞赛方案和我国第一个国际机场候机楼方案。他年轻,富有朝气,设计思想敏锐,有独创精神,他的方案得到了较高的评价。他谦虚、谨慎,能听取各方面意见,善于团结大家共同创作,这些都给我留下了深刻的印象。     

永久的怀念

1980年～2006年,与黄光宇同志长达26年的教学共事和研究合作经历,是我一生中最深刻难忘的回忆之一。     

战友的怀念

百年经典亦辉煌

2005年12月22日国务院发布了《关于加强文化遗产保护的通知》．并决定从2006年起每年六月的第二个星期六为“文化遗产日”。通知首次从“维护国家文化安全”的高度．提出充分认识保护文化遗产的重要性。而作为“石头史书”和“时代镜子”的建筑物．是最重要的不可移动文物．是物质文化遗产中最重要的组成部分。2004年8月份．中国建筑学会建筑师分会曾收到中国建筑学会的来函．     

耐久100年以上的高性能混凝土

以一种新型超细粉取代混凝土中部分水泥，配制水胶比为０．２８的高性能混凝土。若以海水为环境，其极限氯离子含量以钢筋表面氯离子浓度／混凝土界面碱度≥０．６，并假定钢筋保护层厚度为５ｃｍ试验测定了混凝土氯离子扩散系数，经计算，这种高性能混凝土中钢筋脱钝时间为１２０年；而对比的基准混凝土仅为２０年。     

Comparative structural response of two steel bridges constructed 100 years apart

This paper presents a comparative numerical analysis of the structural behaviour and seismic performance of two existing steel bridges, the Infiernillo II Bridge and the Pinhão Bridge, one located in Mexico and the other in Portugal. The two bridges have similar general geometrical characteristics, but were constructed 100 years apart. Three-dimensional structural models of both bridges are developed and analysed for various load cases and several seismic conditions. The results of the comparative analysis between the two bridges are presented in terms of natural frequencies and corresponding vibration modes, maximum stresses in the structural elements and maximum displacements. The study is aimed at determining the influence of a 1 century period in material properties, transverse sections and expected behaviour of two quite similar bridges. In addition, the influence of the bearing conditions in the global response of the Pinhão Bridge was evaluated.     

Urban warming trends in several large Asian cities over the last 100 years

In this paper, the long-term trends in surface temperature in several large Asian cities (Seoul, Tokyo, Osaka, Taipei, Manila, Bangkok, and Jakarta) have been analyzed for estimating the effects of urban warming. A new index, E-HII, is proposed: it is the value obtained by subtracting the temperature data of the four grids around the city from the observational temperature data in the city. Osaka shows the largest E-HII, increasing from approximately 2.4 °C in 1901 to almost 3 °C after 1981. The E-HIIs of Seoul, Tokyo, and Taipei, have increased by 1 °C to 2 °C. Jakarta and Bangkok exhibited a lower E-HII. E-HIIs of Manila and Bangkok have been increasing rapidly after 1961.     

建筑整体平移百年

正建筑是工程技术和建筑艺术的综合创作,是建筑物和构筑物的总称。著名德国哲学家谢林在其名著《艺术哲学》中,有句名言:"建筑是凝固的音乐"。与他同时代的巨人歌德也曾说过:"建筑是一种僵化的音乐"。先哲     

How ideas work: memes and institutional material in the first 100 years of the neighborhood unit

This paper reviews the history of the neighborhood unit idea, primarily in the United States and United Kingdom, as a means to examine how urban design ideas work. It argues that ideas like the neighborhood unit gain their power by framing the institutional material we create to help us cope with work. Institutional material refers to cultural product that conditions human action. Types of institutional material in urban design include practice norms, professional communities, and governance structures. Although the neighborhood unit emerged through a transatlantic network of planners and designers, the institutional material it framed was particular, local, and contingent. Ultimately, the paper argues that the neighborhood unit grew out of institutional material in the early 20th century that itself was influenced by the garden city, and that both neighborhood unit and garden city ideas continued to shape new institutional material in subsequent decades.     

The challenges involved in concrete works of Marmaray immersed tunnel with service life beyond 100 years

Marmaray immersed tube crossing, located at the entrance of Bosphorus Strait of Istanbul, will be one of the unique infrastructure facility bringing great engineering challenges in immersed tunnel technology. The employer requires a minimum design life of 100 years for the immersed tunnel structure that will be under exposure of the highest saline water pressure at the depth of 58 m that has never been experienced yet in the history of immersed tube systems. Since the structural concrete is to be subjected to extremely aggressive environmental conditions during expected long-term service life, the quality assurance of the immersed tunnel has been ensured by setting a series of effective technical requirements taking into account the potential durability risks and predictive models in design phase, outputs of pre-testing activities and potential difficulties at construction period. The objective of this paper is to present some major steps involved in concrete works of this megaproject by giving the highlights from laboratory scale researches to the execution of the work at construction site.

百期寄情

每逢月初,我都盼着看到新一期《建筑创作》,说如饥似渴,似有吹捧之嫌,但确有一种久不相逢,思念不已之情,犹如思念挚友一般.……     

回眸建院六十年

建院六十周年纪念。作为老年职工,希望我写（谈）点情况甲个人往事,依稀犹记;大局变更,则恍同隔世。思绪万千,难以言表。关于建院后的发展辉煌,领导自会总结,我仅谈些个人琐事,供有意究根探底的同志参考。
