三峡工程管理模式及混凝土技术研究

Management Mode and Concrete Construction for the Three Gorges Project

三峡水利枢纽是目前世界上规模最大的混凝土建筑物 ,混凝土总量近 2 80 0× 10 4m3 ,除满足稳定性要求外 ,还需要满足泄洪、发电、航运等方面的特殊要求 ,具有结构复杂、施工强度高、技术标准高等特点。通过 10年的工程实践 ,三峡工程建设管理初步形成了具有三峡工程特色的管理模式。为保证混凝土优质快速施工 ,研究和决策了若干新技术和新工艺 。

The Three Gorges Project (TGP) is the largest concrete structure in the current world. The Project, with a total amount of approximately 28 million m 3 of concrete, is characterized by complicated structure, intensive construction and high technical standards, which should not only meet the requirements for stability but also meet the special requirements for flood releasing, power generation and navigation improvement. Through a decade of engineering practice, a management mode with the TGP's characteristics has been formed in the TGP construction management. Various new techniques and technologies have been used to ensure the concrete quality. Design, construction and management measures adopted for the concrete works of the Project are discussed in this article on an overall basis.
