基于深基坑施工期风险评估的安全指数研究

针对传统风险评估方法的局限性,提出基于深基坑工程施工期风险评估的安全指数体系,该体系考虑了与工程安全相关的施工、地质、天气、环境等各种影响因素,提出以安全指数为代表的5个影响指数及相应计算、评估方法。通过该体系可以直观了解当前深基坑工程安全状况及相应各影响因素,其中安全指数反映了整个工程的当前总体安全状况;工程安全影响指数反映出施工、环境、天气、地质等因素对当前工程影响程度;施工、环境、天气、地质等4个影响指数反映了影响工程安全状况的主要因素与重要因素。

Study of Safety Index System Based on Risk Assessment in the Construction of Deep Excavation Project

This paper proposes safety index system based on risk assessment during the construction of deep excavation due to the limitation of traditional risk assessment.The system includes some influential factors which closely related to the safety of deep excavation engineering such as construction,geology,weather and environment.Meanwhile,this paper proposes several influential indexes include safety index and other five influential indexes and computing methods.The safety condition of deep excavation engineerin...
