浅谈建设监理中的安全控制

目前我国大中型建设项目和国家重点工程都实行了建设监理制,在控制工程质量、安全、造价和工期等方面均取得了很大成效。本文阐述了建设监理中安全控制的内容,并针对施工中的不安全因素提出了预防对策。     

中国安全文化建设的时代背景——兼谈21世纪安全科技文化新观点

虽然,职业安全卫生在其硬件、管理及人的行为规范方面取得了较大成效,但在世界范围内,意外职业伤亡事故的严峻形势仍令人十分担忧。随着科技进步、工业发展和社会文明的要求,本世纪８０ 年代,有人提出安全文化的理论。在国内一些工业企业中,大量的实践证明,安全文化建设是做好职业安全卫生工作的基础,也是大众安全及社区安全的基础。笔者分析了中国安全文化建设产生的背景,研究了弘扬和传播安全文化的途径,提出了当代人应树立跨世纪的安全科技文化新观点     

工业综合开发区环境影响后评估探讨

环境影响后评估是提高环境影响评价有效性的重要手段。工业综合开发区环境影响不同于一般建设项目环境影响,因而后评估具有不同的特点。该文以福建省龙海角美工业综合开发区环境影响后评估试点工作为例,介绍了工业综合开发区环境影响后评估的主要内容和技术路线,阐述了对环境影响后评估的理解和体会。

提高环评报告书质量加快浙江省环境影响评价有效性建设

影响环境影响评价(EIA)有效性的因素较多．如相应的政策法规、管理机制和技术的正确性等。文章从环评技术角度出发,以抽样选取的浙江省1997～2001年间完成的100本环评报告书(EIS)为统计对象．按建设项目环保审批6项原则为依据,从产业政策符合性、选址与总图布局合理性、清洁生产、达标排放、总量控制、区域环境质量可达性等方面进行分析．评估了浙江省EIA有效性,探讨了目前EIA中存在的问题及原冈,提出了一些提高EIS质量、加快浙江省EIA有效性建设的建议     

生态县评价体系及持续发展战略的研究

在生态县规划研究中,以复合生态系统理论为指南,探讨了生态县的内涵和评价标体系,并确定了以生态农业为基础,以生态型工业为主导,以社会调控为保障,依靠科技进步,寓环境建设于经济社会发展之中的建设生态县的战略,在近年实践中初见成效。     

基于两阶段模糊熵权的震灾抢修抢建价值评估模型

面对地震对工程的破坏与抢修抢建需求,提出一种两阶段模糊熵权的抢修抢建工程价值评估模型。探究地震作用下抢修抢建工程价值特征体系的参数、变化趋势等特征,给出工程项目价值指标的混合判断矩阵,集成模糊熵权方法对工程项目价值指标阶段、准则阶段进行层次化评估,确定工程项目的抢修抢建相对价值系数。模型应用于震后抢修抢建案例,得到工程项目隐含的权值信息,据此得到抢修抢建案例的价值系数及执行序列。     

Prioritizing prevention opportunities in the Washington State construction industry, 2003-2007

Objective

This study compares construction industry groups in Washington State by injury severity and cost, and ranks industry groups according to potential for prevention.

Methods

All Washington State workers' compensation compensable claims with date of injury between 2003 and 2007 were classified into North American Industrial Classification System (NAICS) industry groups. Claims were then aggregated by injury type and industry groups were ranked according to a prevention index (PI). The PI is the average of the rank orders of the claim count and the claim incidence rate. A lower PI indicates a higher need for prevention activities. The severity rate was calculated as the number of days of time loss per 10,000 full-time equivalents (FTEs).

Results

For all injury types, construction industry groups occupy 7 of the top 15 PI ranks in Washington State. The severity rate among construction industry groups was twice that for non-construction groups for all injury types. Foundation, structure, and building exterior contractors (NAICS 2381) ranked highest in prevention potential and severity among construction industry groups for most common injury types including falls from elevation, fall on same level, struck by/against, and musculo-skeletal disorders of the neck, back, and upper extremity (WMSDs). Median claim costs by injury type were generally higher among construction industry groups.

Conclusions

The construction industry in Washington State has a high severity rate and potential for prevention. The methods used for characterizing these industry groups can be adapted for comparison within and between other industries and states.

Impact on Industry

These data can be used by industry groups and employers to identify higher cost and higher severity injury types. Knowledge about the relative frequencies and costs associated with different injury types will help employers and construction industry associations make better informed decisions about where prevention efforts are most needed and may have the greatest impact. The results of this study can also be used by industry stakeholders to cooperatively focus on high cost and high severity injuries and explore best practices, interventions, and solutions as demonstrated by efforts to prevent musculoskeletal disorders in masonry (Entzel, Albers, & Welch, 2007). Initiating construction industry groups to focus on high cost and high severity injuries may also help prevent other types of injuries.     

地铁项目安全绩效关键影响因素分析研究

在分析研究地铁安全事故案例的基础上,识别出对地铁项目安全绩效的48个关键影响因素,将这些影响因素归为五大类,即项目参与各方对安全的影响程度、人员的不安全行为及不安全状态、材料的不安全状态、机械/设备的不安全状态和现场环境的不安全状态;采取调查问卷的方式,运用结构方程建模得出各个指标的重要度及各指标之间的相互影响。研究结果表明:"项目参与各方对安全的影响程度"和"现场环境的状态"对地铁安全绩效的贡献最大,同时,其他因素也有较强的影响,在地铁施工中应以此为重点,加强安全防范。
