深基坑支护结构设计与施工安全风险评估

Key Points

• This research aims to explore the principles and design types of deep excavation support structures and establish a safety risk assessment framework.
• Discusses characteristics of deep excavation projects and common risk sources.
• Analyzes design points of mainstream support structures such as pile retaining.
• Develops a risk assessment model using risk matrix method and analytic hierarchy process.
• Identifies and quantitatively evaluates five major categories of risk factors.
• Proposes comprehensive risk control strategies for high-risk stages.
• Suggests that integrating refined design with dynamic and quantitative risk assessments is crucial for safe and efficient implementation.
