Genetic Analysis of Concrete Crack in Hydroelectric Station's Plant Based on FEM

摘要

This study is mainly in temperature-control and anti-cracking of plant concrete in hydroelectric station. By means of FEM of three-dimension thermal creep stress and imitating construction progress, an emulator calculation is performed from construction period to operation period and distribution regularity of thermal creep stress is brought to light in the theory. The text described the developing process of concrete's temperature and thermal stress, and then combined concrete's time-varied thermotics and mechanics performance to analyze the possibility of yielding crack in different period and position.
