摘要
建筑工程项目现场条件复杂,各工种交叉作业,极易产生安全事故。本文结合预先危险分析方法(PHA)和作业条件危险性评价方法(LEC)对建筑工程项目的安全评价问题展开研究。首先是从指标量化和危险性等级多重约束分级的角度改进了PHA-LEC方法,并引入POSE四维度分析方法来辅助解决PHA-LEC改进方法中包括参数取值和计算规则在内的三个核心问题。随后,本文设计了基于PHA-LEC改进方法的建筑工程项目安全评价流程,提出要加强基础数据的收集和危险源数据库标准化建设工作。最后就该安全评价流程的应用提出了三点建议,以加强建筑工程项目安全评价工作的效率和有效性。
The site conditions of construction project are complex, and have various types of cross operation. It＇ s very easy to produce safety accidents. In this article the construction project safety evaluation problems were studied based on a method combination including preliminary hazard analysis method （PHA） and operating condition risk assessment method （LEC）. The first step was to improve PHA-LEC method considering the index quantification and multiple constraint risk grade classification, and to solve three core problems including parameters and calcula- tion rules by introducing POSE four dimension analysis methods. Subsequently, a construction project safety evalu- ation process was designed based on improved PHA-LEC method, and it was put forward to strengthen basic data collection and standardization work of hazard database. Finally, three suggestions on safety evaluation process ap- plication were proposed, in order to strengthen the safety evaluation efficiency and effectiveness on construction pro- ject.
