摘要
自2015年起,国家大力提倡推行城镇老旧小区综合性改造工程,随着愈来愈多的改造项目逐渐展开,暴露出很多施工安全问题,尤其是高处坠落引发的安全事故频发。为做到未雨绸缪,本文以兰州市部分老旧小区改造项目为研究对象,运用文献调研法、层次分析法(AHP)、作业条件危险性评价法(LEC评价法)、模糊综合评价法(FCE)等方法,在施工前对老旧小区改造项目施工现场存在可能引发高处坠落事故的安全隐患进行识别;应用FCE法,对实际项目的整体安全程度进行定量评价;运用LEC法,对具体的安全隐患因素进行排序;运用AHP法,对具体工作场景的安全权重进行确定;根据评价结果,针对性地制订出应对措施,系统地提高安全管理水平,对小区改造项目的实施具有一定的指导意义和应用价值。
Since 2015,the state has vigorously advocated the implementation of the project of a comprehensive transformation of urban old residential areas.With the gradual development of more and more reconstruction projects,many construction safety problems have been exposed.In particular,safety accidents caused by falling from height occur frequently.In order to make a good plan in advance,this paper takes the reconstruction projects of some old residential areas in Lanzhou as the research object,and uses the methods of literature investigation,analytic hierarchy process(AHP),risk assessment of operating conditions(LEC evaluation)and fuzzy comprehensive evaluation(FCE)to identify the safety hidden dangers that may cause serious fall accidents at the construction site of the reconstruction project of the old residential area before construction.Apply the FCE method to quantitatively evaluate the overall safety degree of the actual project;use the LEC method to sort the specific hidden safety factors;use the AHP method to determine the safe weight of the specific work scene;according to the evaluation results,formulate corresponding measures to systematically improve the level of safety management,which has a certain guiding significance and application value for the implementation of the community reconstruction project.
