高速公路小煤窑采空区路基综合勘察与评价

采空区是公路建设中一种特殊的地质病害，特别是小煤窑采空区，由于无规划、无序、反复地开挖，故小煤窑采空区勘察与评价有较多不确定性。在公路工程地质勘察中采用综合勘察方法，查明采空区分布范围并评价其对公路工程危害程度及稳定性，对高速公路建设非常重要。本文结合安徽省铜陵至汤口高速公路具体工程实例，探讨小煤窑采空区综合勘察与评价。

Confined vapor explosion in Kaohsiung City – A detailed analysis of the tragedy in the harbor city

On the midnight of July 31st, 2014, a catastrophic vapor explosion occurred in the downtown of Kaohsiung city. The incident was initiated from a leak of an underground pipeline transporting pressurized propylene liquid. Analysis of pipeline operation logs and pipeline break release modeling suggested that at least 90,000 kg of propylene leaked, entered the underground trench and spread into the trench 4.5 km in distance before meeting an ignition source some three hours later after the leak. The ignition caused a significant confined vapor explosion which blew out the road above the underground trench, damaged more than one hundred vehicles on the road with thirty two fatalities and more than three hundred injuries. This article will first describe the background of the pipeline installation follows by an in-depth look at the explosion incident covering the events leading to the explosion, explosion damage, cause of the leak, spread of the leak, identification of a probable ignition source, and root causes in safety culture. Finally, lessons learnt and recommendations are given to prevent and mitigate the occurrence of similar incidents.

居民对室内空气质量安全认知程度的调查研究

为了解山西省城市居民对室内空气质量安全的认知情况和室内空气质量现状,在山西省太原、大同、晋城和吕梁随机选取786户居民进行问卷调查,并对有检测意愿的86户居民进行室内甲醛含量检测.结果表明,山西省居民室内空气质量安全认知得分15.37,得分率为51%;山西省居民平均室内甲醛浓度(0.197 mg/m3)超过国家标准(0.1 mg/m3);四市中太原市的情况最好.山西省居民在室内空气质量安全方面的认知水平和室内空气质量都不高,为保障山西省居民健康,应对山西省城市居民进行室内空气质量安全知识的普及.     

对建立第三方事故调查机制的探讨

事故调查的根本目的在于查找事故的可能原因并提出事故的预防措施,而事故调查的独立性对此根本目的起关键作用。我国安全生产管理体制建设起步较晚,事故管理机制发展不成熟,与国外先进事故调查理念相比,我国事故调查机制缺乏独立性的保障,主要表现在技术调查与司法调查未能分离、事故调查报告未能完全公开、事故调查的客观性保障不足,限制了我国事故调查水平的进一步提高。通过分析国外第三方事故调查的机制的优势并结合我国国情,从第三方事故调查的任务、人员编制、人员培训、责任与权利、法律义务等方面提出我国第三方事故调查机制的框架,并规划了构建第三方事故调查的三阶段进程及其主要内容,以逐步实现第三方事故调查的公正、客观、高效,更好地促进我国安全生产管理水平的提高。     

电熨斗过热故障火灾痕迹特性的研究

通过火灾模拟实验,研究电熨斗发生过热故障后底板的火灾痕迹特性。根据底板的温度分布,应用DTA、TG、SEM、EDS、硬度分析和金相分析等方法,系统分析、归纳、总结电熨斗底板火灾痕迹的材料性能变化规律。研究表明,过热故障电熨斗的火灾痕迹,在宏观形貌、硬度分布和显微组织特征等方面,均显著区别于火烧电熨斗的火灾痕迹。结果为火灾原因调查提供新的技术依据,可应用在火灾现场勘验,物证提取与鉴定工作中。

Current Status of Manufacturing Hazardous Waste in Shanghai

It is difficult to manage the manufacturing hazardous waste （MHW） which is generated from a huge amount of complicated sources and causes very serious pollution. Therefore more and more attention has been paid to MHW pollution. Shanghai, as an industrial and economic center and an international metropolis in China, has a vast industrial system spanning a multitude of sectors, which generates MHW not only in a huge magnitude but also in a large variety of types from complicated sources, resulting in severe pollution. In 2003, the production of MHW in Shanghai is about 3.96 × 10^5 ton, involving 33 indices. Most of MHW in Shanghai is treated and disposed of, but a significant portion is not handled properly and effectively. This paper carries out infield investigation on the current status of MHW production and treatment in Shanghai, and puts forward scientific proposals that Shanghai should facilitate cleaner production and minimize haz- ardous waste; strictly enforce hazardous waste registration system, strengthen monitoring the certified enterprises; strengthen intent disposal center construction and realize hazardous waste reclamation; accelerate establishing the technical criteria and the management policy, promote the research and development on the treatment and disposal technology, and strengthen information management, thus realizing integrated management on MHW pollution.
