高速公路简支桥梁施工技术及安全风险评估

Construction Technology and Safety Risk Assessment of Expressway Simply Supported Bridge

为保障高速公路建设安全,分析了简支桥梁施工的技术要点,包括扩大基础施工、桩基础施工、桥墩施工、桥台施工、梁板预制及安装、桥面施工等。提出了施工风险控制策略:制定风险应对方案,完善安全风险管控,做好施工技术交底,加强工程安全风险评估。以国道修复某工程项目为例,建立了简支桥梁施工安全预警机制并进行危险源管控,通过完善安全风险评估体系,制定高效的管理策略,促进桥梁施工有序进行。

In order to make sure the security of expressway construction,the study analyzes the technical points of simply support bridge construction:the expansion of foundation construction,pile foundation construction,pier construction,abutment construction,beam and slab prefabrication and installation,and deck construction,etc.Then the study proposes the strategies for construction risk control:to formulation risk corresponding scheme,perfect security risk control,do well in construction technical disclosure,and promote engineering security risk evaluation.Through taking an engineering project of national highway restoration as an example,the early-warning mechanism of construction security of simply supported bridge is established,and hazard source control is carried out.High efficient management strategies are formulated through perfect security risk evaluation system to promote orderly bridge construction.
