工程监理博弈行为分析与对策研究

工程建设监理制度对提高工程项目的质量。促进建筑业的健康发展发挥了重要的作用。但与发达国家相比。我国工程建设监理制度仍不够完善。从博弈论的观点出发。分别建立了监理单位和承包商之间的两方博弈模型以及业主、监理单位和承包商之间的三方博弈模型。并在分析模型均衡解的基础上，得到了完善工程建设监理制度。提高工程项目质量的政策建议。     

Sustainable management of demolition waste—an integrated model for the evaluation of environmental, economic and social aspects

A model is presented for evaluating waste management systems for their contribution to a sustainable development, including environmental, economic and social aspects. The model was tested in a case-study, where groups of long-term unemployed people were offered both education on environmental issues and practical work with the recovery and recycling of building and demolition waste as a form of vocational development. Application of the suggested model revealed the overall effects on sustainability of different methods of waste management. In addition, negative aspects of the systems analysed were identified, which led to discussions about possible improved practices within the waste management systems. Two of the waste management systems investigated (the recycling of steel and re-use of sanitary porcelain) showed a potential contribution to sustainable development in all of the aspects studied. Preparing bricks for re-use showed the largest potential for eco-efficiency, but had negative effects on sustainability from the social perspective of health and the working environment. The possibility of further use of the model and the remaining obstacles to such analyses are discussed. One observation is that the data collection needed to perform this kind of sustainability analysis is resource-demanding, and that it would therefore be better to identify a smaller number of key indicators.

某城市建筑泥浆污染现状调查研究

以某城市为例,研究城市建筑泥浆的污染现状,并分析泥浆受到污染的原因.结果表明:对照《地表水环境质量标准》(GB 3838-2002)中的Ⅳ类标准限值,调研的4个工地泥浆水全部超标;该城市地层土壤中的有机质、总氮、总磷含量高是泥浆水超标的重要原因,工地制浆使用的地表水和污水也不能满足Ⅳ类水质的要求.在建筑工地的管理中,应...     

都江堰市生态市建设

将都江堰市建设成我国西部第一个国家级生态市,该市地处我国大地形中第一阶梯向第二阶梯过渡地带,具有物种、生态系统和景观多样性优势;是古代著名水利工程都江堰的所在地,对于成都市和成都平原起着水资源调控和生态屏障作用。该市是著名风光名胜区和旅游城市,具有城市、农村、高中山、丘陵、平原、水域等广泛的功能示范意义。都江堰市具有建成生态市的良好自然条件和社会经济基础,但也面临着严峻的挑战。生态市建设的重点是要保护和发挥该市亚热带的自然生态系统的服务功能,开发与生态良性循环相协调、与环境友好的产业,构建起循环经济的体系和经营机制,建成风光秀美、经济发达、社会文明、人居环境舒适的城市。     

国内外大型水电工程生态环境监测与保护

简要介绍了世界银行对水电工程的环境政策,概述了埃及阿斯旺、巴西伊泰普、中国的二滩和三峡等四个世界著名水电站的长期环境监测计划和减少负面影响的对策。水电工程对周边环境会产生正面或负面影响,对大型水坝的负面影响作了集中的阐述。埃及的阿斯旺高坝建于20世纪60年代, 当时人们对生态环境影响问题还没有引起重视。长期的生态环境监测结果表明,一些环境影响比如河床侵蚀等实际上被过分夸大,而另外一些,如对传统的制砖业带来的影响又被忽视;巴西的伊泰普水坝在兴建过程中注意了采取措施减少负面影响,如在库周地区植树造林,兴建生物屏障,建立自然保护区,实施动物救护等;中国的二滩水电站由世界银行贷款兴建,并执行了世界银行的环境政策来降低负面影响;这些大型水电工程兴建中的经验给在建的三峡工程提供了有益的借鉴,一系列的环境保护措施正在实施,世界上最大的生态环境监测网络已在三峡库区及相关地区建成。

Exploring the perceived influence of safety management practices on project performance in the construction industry

Although safety management is known to be vital to construction projects, very few studies have solicited views from construction practitioners about their perceptions of which safety management practices (SMPs) are important to construction projects and related to project performance. An empirical study was undertaken in Hong Kong in order to shed more light on this topic. In the study, the importance levels of 15 popular SMPs and five project performance criteria were rated by 232 respondents. An exploratory factor analysis was conducted, and three SMP categories - information, process, and committees - were extracted. Of these three categories, safety management process was perceived by the construction practitioners as being the most important, followed by safety management information and committees. Moreover, the effect of the three SMP categories on a composite project performance variable was tested using hierarchical regression analysis. Results indicate that the “information” and “committees” categories were associated with project performance positively and significantly. One of the major conclusions of the study is that the construction industry has paid relatively less attention to safety management committees, which were empirically analyzed as having a strong perceived impact on project performance. In order to improve project performance, construction companies should promote the criticality of safety management committees.
