【摘要】：HSE是健康(Health)、安全(Safety)和环境(Environment)三位一体的动态管理体系。随着科学技术的发展,HSE管理模式受到越来越多的重视。高铁桥梁工程设计时速高、设计荷载大、施工技术复杂、施工环境恶劣、施工现场劳动力密集,施工作业过程蕴藏着多种不安全因素,存在对人员身心健康、人员与机具设备安全和生态环境等不同程度和不同形式的影响和危害,即存在不同程度、形式各异的HSE风险。因此,从事故本源对高铁桥梁施工过程HSE实施情况进行系统分析评价,采取控制措施,以降低工程事故发生率,进而保障人员安全、健康,保护沿线生态环境。论文对近几年发生的桥梁安全事故分布状况及其特点进行统计分析,寻找桥梁施工作业HSE风险来源,在此基础上,结合危险源研究理论、本质安全系统理论、事故致因理论等,从事故源头剖析了高铁桥梁施工领域危险源的引发机理,建立了基于健康、安全、环境的桥梁施工风险指标;论文采用BP神经网络方法构建一种科学实用的高铁桥梁施工HSE评价模型,并用MATLAB软件实现评价过程,以XX桥梁施工过程HSE实施情况为研究对象进行实例验证,测试结果表明本文所构建HSE评价模型的预测精度较高,具有良好的泛化能力,可用于实际工程应用效果分析。论文通过对高铁桥梁施工HSE风险管理研究,表明将HSE管理体系运用于高铁桥梁施工过程管理具有指导意义,提升高铁桥梁施工HSE管理水平,保护施工作业人员生命和财产安全。
[Abstract]:HSE is a three-in-one dynamic management system for health, safety and environment. With the development of science and technology, more and more attention has been paid to HSE management model. High-speed high-speed railway bridge engineering design speed, design load, complex construction technology, construction environment, construction site labor density, construction process contains a variety of unsafe factors, the existence of physical and mental health of personnel, There are different degrees and forms of HSE risks in different degrees and forms of influence and harm on personnel and equipment safety and ecological environment. Therefore, the implementation of HSE in the construction process of high-speed railway bridge is systematically analyzed and evaluated from the source of the accident, and the control measures are taken to reduce the accident rate, and then to ensure the safety and health of the personnel and to protect the ecological environment along the line. This paper makes a statistical analysis on the distribution and characteristics of bridge safety accidents in recent years, and finds out the source of HSE risk in bridge construction. On this basis, combining with the theory of risk source, the theory of essential safety system, the theory of accident cause, etc. From the source of the accident, this paper analyzes the cause mechanism of the hazard source in the field of high-speed railway bridge construction, and establishes the risk index of the bridge construction based on health, safety and environment. The paper uses BP neural network method to construct a scientific and practical HSE evaluation model of high-speed railway bridge construction, and realizes the evaluation process with MATLAB software, and takes the HSE implementation of XX bridge construction process as an example to verify. The test results show that the HSE evaluation model constructed in this paper has high prediction accuracy and good generalization ability. It can be used to analyze the effect of practical engineering application. Through the research on HSE risk management of high-speed railway bridge construction, the paper shows that it is of guiding significance to apply HSE management system to the construction process management of high-speed railway bridge construction, to improve the HSE management level of high-speed railway bridge construction, and to protect the life and property safety of construction workers.
