Research on safety risk identification and evaluation of rural self-built houses
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.
