Analysis on Temperature Control and Crack Preventing in Wudu RCC Dam during Construction
摘要
Abstract
On the basis of cracking mechanism research of RCC dams during the period of construction, the distributions of temperature and thermal stress in dam body under different temperature control measures are obtained for Wudu RCC Dam after adopting the thermal and mechanical parameters obtained by the feed-back analysis for simulation. The results under different temperature control measures are compared, particularly with insulation and without insulation. The corresponding temperature control measures are put forward to deal with the typical cracking risks. The study provides a basis for the decision-making of crack prevention during the construction period.关键词
