High Intensity Concrete Construction Technology and Management Mode of Large-Scale Hydropower Project

TLDR
The Three Gorges Project (TGP) as discussed by the authors is the largest concrete construction in the present world and is characterized by complicated structures, intensive construction and high technical standards, which should meet the requirements not only of stability but also of special flood releasing, power generation and navigation improvement.
Abstract
The Three Gorges Project (TGP) is the largest concrete construction in the present world. The project, with a total amount of approximately 28 million m3 of concrete, is characterized by complicated structures, intensive construction and high technical standards, which should meet the requirements not only of stability but also of special flood releasing, power generation and navigation improvement. Through engineering practice, a management mode that embodies the characteristics of TGP construction has been formed. Various new techniques and technologies have been used to ensure the concrete quality. Design, construction and management measures were adopted for the concrete works of the project. It is shown that, a scientific and reasonable management mode is crucial for planning, controlling and coordinating a large-scale construction project, which is the key to the success of hydropower development.

Keeping it cool at Three Gorges

TL;DR: Dai Huichao explains how the size and surrounding environment of the Three Gorges dam required special concrete pouring and cooling solutions as mentioned in this paper. But the authors did not consider the effect of temperature on the concrete pouring process.

Temperature Crack and Stress Calculation of Ultra-long Concrete Constructions

TL;DR: It is completely possible in theory for ultra-long concrete structure not set temperature expansion joints, as long as the obtained tensile stress is not greater than tensile strength of material, it can ensure the structure will not crack and seamless construction of any length can be completed.
