高寒低氧环境公路桥涵工程施工安全技术优化

Optimization of Construction Safety Technology for Highway Bridge and Culvert Engineering in High Cold and Low Oxygen Environment

摘要

高寒低氧环境（最冷月月平均气温-3℃~-10℃、海拔≥2000m，氧气含量每升高1000m下降10%），具有低温严寒、氧气 匮乏、地质复杂、生态脆弱等特征，给公路桥涵施工安全带来诸多挑战。本文结合相关规范及高原施工实践，系统分析施 工安全核心问题，明确优化原则，从人员防护、机械适配等六个维度提出针对性优化措施，强化组织、技术等四大保障体 系，形成全方位可操作的安全技术优化方案，为该区域公路桥涵工程安全、高效、绿色推进提供技术支撑，助力交通基础 设施高质量建设。

Abstract

The alpine and hypoxic environment (the coldest month with monthly average temperature of -3 ℃~-10 ℃, altitude ≥ 2000m, and oxygen content decreases by 10% for every 1000m increase) has the characteristics of low temperature and severe cold, oxygen deficiency, complex geology, fragile ecology and so on, which brings many challenges to the safety of highway bridge and culvert construction. Combined with relevant specifications and plateau construction practice, this paper systematically analyzes the core issues of construction safety, defines the optimization principles, puts forward targeted optimization measures from six dimensions of personnel protection and mechanical adaptation, strengthens the four guarantee systems of organization and technology, and forms a comprehensive and operable safety technology optimization scheme, which provides technical support for the safe, efficient and green promotion of highway bridge and culvert projects in the region, and helps the high-quality construction of transportation infrastructure.
