Concrete construction technology in Phase II dam of Three Gorges Project

摘要

Concrete construction is one of the most important and most challenging projects in the Three Gorges Project (hereinafter called TGP) Construction since it features mammoth amount, high intensity, complex structure, and strict requirement in the Phase II dam and powerhouse construction. The paper is intended to analyze difficulties of the quality control of concrete construction, to systematically present the concrete construction scheme and temperature control measures to prevent concrete cracks, and to brief concrete construction progress and quality control effect.
