摘要:桥梁精益建造数据管理能力成熟度模型对于评估桥梁精益建造数据管理服务能力，提升桥梁工程项目管理能力有着重要意义。本文结合现有的数据管理成熟度模型和工程管理相关理论，基于初始级、受管理级、稳健级、量化管理级、优化级五个阶段构建桥梁精益建造数据管理能力成熟度模型，并以沉香大桥项目为例对模型进行应用探析。从数据战略、治理、架构、应用、安全、质量、标准、生存周期8个能力域，28个能力项探究数据管理能力成熟度的评价和优化提升的方法，为我国桥梁工程的精益建造的发展和创新提出针对性建议。

Abstract: The capability maturity model of bridge lean construction data management is of great significance to assess its service capability and improve the bridge engineering project management capability. This paper combines the existing data management maturity model and engineering management related theories to construct a capability maturity model of bridge lean construction data management based on five stages: initial level, managed level, robust level, quantitative management level, and optimization level. Taking Shenxiang Bridge project as an example, this paper further explores the application of the model. Applied to the Sinkiang Bridge project, the evaluation and optimization methods of data management capability maturity were explored from 8 capability domains and 28 capability items: data strategy, governance, architecture, application, safety, quality, standard, and life cycle. At the end, the paper proposes some suggestions for the development and innovation of lean construction of bridge engineering in China.
