Identification and prevention and control measures of safety risks in deep foundation pit support construction
深基坑支护施工安全风险识别与防控对策

摘要

深基坑支护施工过程中，受地质条件、施工技术、周边环境等多因素影响，安全风险频发，成为城市基础设施建设中的重大隐患之一。本文以深基坑支护施工安全为研究核心，系统梳理常见的风险类型，聚焦坍塌、渗漏、基坑变形等关键隐患，从施工准备阶段、支护结构设计、现场管理到突发事件应对，构建一套针对性强、可操作性高的风险识别与防控体系。在此基础上，提出智能监测、分级管理、应急联动等防控策略，力图提升施工安全保障水平，为类似工程提供理论参考与实践借鉴。

Abstract

During the construction of deep foundation pit support, safety risks occur frequently due to the influence of multiple factors such as geological conditions, construction technology, and surrounding environment, making it one of the major hidden dangers in urban infrastructure construction. Focusing on the construction safety of deep foundation pit support as the core of the research, this paper systematically sorts out common risk types, focuses on key hidden dangers such as collapse, leakage, and foundation pit deformation, and constructs a set of risk identification and prevention and control system with strong pertinence and high operability, covering the construction preparation stage, support structure design, on-site management, and emergency response. On this basis, it puts forward prevention and control strategies such as intelligent monitoring, hierarchical management, and emergency linkage, aiming to improve the level of construction safety assurance and provide theoretical reference and practical experience for similar projects.
