建设项目安全领导力与安全文化提升:以妈湾隧道工程为例

Safety Leadership and Safety Culture Enhancement in Construction Projects:the Case of Ma Wan Tunnel Project

不安全行为是建筑事故的主要和直接致因,传统基于行为安全的安全管理提升方法仅局限于奖惩措施,持续性有限,且效果会随着时间增加而显著降低。旨在基于施工安全LCB(领导力—文化—行为)理论设计针对性的LCB提升方法,通过LCB综合提升实现建设项目安全管理的持续改善。首先,使用LCB测评量表对案例项目在安全领导力、安全文化和安全管理行为上的表现进行评价,确定提升目标。然后,依据LCB理论确定了5项提升措施,并经过现场调研、访谈形成了提升方案。最后,经过观察期LCB测评证实了提升方案的有效性,并进一步进行跟踪期LCB测评证实了提升效果的持续性。结果表明,所制定的提升方案对关注尊重、教育培训、安全教育三个LCB维度实现了显著和持续改善。所述方法丰富了LCB理论与实践,可作为类似项目进行安全管理提升的参考。

Construction accidents are primarily and directly caused by unsafe behavior.Traditional safety intervention techniques based on behavioral safety are restricted to rewards and punishments,which have a limited capacity for sustainability,and the intervention effect declines noticeably as intervention time increases.Based on the(Leadership-Culture-Behavior)LCB theory of construction safety,the aim of this study is to develop a targeted LCB intervention approach,and through comprehensive LCB intervention,to enhance the safety management of construction projects.In order to establish the goals of the intervention,the case project’s performance in terms of safety leadership,safety culture,and safety management behavior was first assessed by using the LCB measuring scale.Following the identification of five interventions using LCB theory,an intervention program was developed based on on-site research and interviews.Finally,LCB measurement during the observation period and another LCB measurement during the follow-up period were undertaken to validate the sustainability of the intervention effects.The results indicated that the developed intervention program achieved significant and sustained improvements in the three LCB dimensions of attention to respect,education and training,and safety education.The methods described in this paper can be used as a reference for similar programs to conduct safety interventions,enriching LCB intervention practices and further deepening LCB theory.
