摘要
该文采用风险评估理论对农村自建房安全风险进行了识别与评估,通过对2013年至2022年间97起倒塌事故的统计分析,总结出导致非自然灾害下房屋倒塌的主要危险因素,包括不合格建材、地基处理不当、设计不合理、施工质量问题、施工超载、违规操作、承重墙拆除、无资质施工队伍和缺乏监管等.采用故障树分析法构建了风险评估模型,并通过基本事件重要度计算识别关键倒塌因素,进而对评估指标体系进行了实例验证.研究提出了针对性的风险管理建议,以提升农村自建房的安全水平.
Abstract
This study aims to identify and assess the safety risks of rural self-built houses through the lens of risk assess-ment theory.By conducting a statistical analysis of 97 collapse accidents occurring between 2013 and 2022,the research identified the main dangerous factors leading to house collapse under non-natural disaster conditions,including the use of substandard building materials,improper foundation treatment,unreasonable design,construction quality issues,overloa-ding during construction,unauthorized operations,removal of load-bearing walls,construction teams lacking qualifica-tions,and lax regulatory oversight.A fault tree analysis method was employed to construct a risk assessment model,and key collapse factors were identified through the calculation of basic event importance.The research further validated the assessment indicator system through an example analysis.Finally,targeted risk management recommendations were pro-posed to enhance the safety level of rural self-built houses.
