摘要
为确保三峡工程右岸大坝在2006年6月前全线达到坝顶高程185m，从大体积混凝土的温度控制、浇筑强度和质量等方面对三峡三期工程采用3m升层的混凝土施工技术和实施措施进行了研究，详细介绍了研究成果度其在三峡三期工程中的成功应用。这项技术突破了大坝柱状块分层厚度1．5-2．0m的施工惯例，并为大体积混凝土3m层夏季施工积累了难得的工程经验。
In order to ensure that the right dam of the Three Gorges Project will be built to the elevation of 185 m before June,2006,researches on 3-m lift concrete construction technology for the Stage-3 Three Gorges Project and on measures to be taken for applying this technology were conducted in temperature control,placement intensity and construction quality of mass concrete.This paper presents in detail the research results and their successful application in the Stage-3 Three Gorges Project.This technology has broken through the usual practice of columnar dam blocks being placed with every lift thickness of 1.5-2.0 m,and accumulated engineering experience for 3-m lift mass concrete to be placed in summer.
