摘要
文中通过P×C法开展基坑支护施工过程中的危险评估及分析,结果表明,二级指标的危险性得分范围为55.24~71.44,危险性等级主要介于Ⅰ-Ⅲ级;一级指标的危险性得分在57.12~67.25,危险性等级主要介于Ⅰ-Ⅱ级;基坑支护施工的整体危险性得分为65.98,危险性等级为Ⅱ级,说明基坑施工条件一般,施工风险较小,为现场安全施工奠定了理论基础。
To ensure the safety of foundation pit support construction,this article uses P×Hazard assessment and analysis during the construction process of foundation pit support using method C.The analysis results show that the risk score range of the secondary indicators is 55.24~71.44,and the risk level is mainly between level I-III;The risk score range of the first level indicator is 57.12~67.25,with the risk level mainly ranging from level I to level II;Finally,the overall hazard score of foundation pit support construction is 65.98,with a hazard level of II,indicating that the construction conditions of the foundation pit are average and the construction risk is relatively low,laying a theoretical foundation for on-site safety construction.
