基于云模型的建筑施工现场安全综合评价研究

Research on Comprehensive Evaluation of Safety in Construction Site Based on Cloud Model

建筑作业一般为立体交叉、持续作业,作业类型多且工序复杂,这些特点就导致在施工作业中会存在许多危险有害因素,稍有疏忽就会发生事故。结合本单位工程实例,首先辨识分析危险源,将施工现场发生事故的原因归纳为四大类:人、施工设备、管理、作业环境,然后建立基于云模型的包含4个一级、18个二级评价指标的建筑施工现场安全评价体系。

Construction operations are generally tridimensional intersecting and continuous operation.There are many types of operations and complex processes.These characteristics lead to occurrence of many dangerous and harmful factors in construction operations.A slight negligence will result in an accident.Combining with the engineering examples,the sources of dangers are identified and analyzed firstly and the causes of accidents at the construction sites are classified into four categories:people,construction equipment,management and operating environment.Then based on cloud model,safety evaluation system for construction sites containing 4 primary and 18 secondary evaluation indexes are established.
