高温季节碾压混凝土坝强约束区温控防裂方案研究
Study on Temperature Control and Crack Prevention Scheme of Strong Constrained Zones in Roller Compacted Dams during High Temperature Season
摘要
Abstract
High temperature season lasts longer comparatively in southwest of China,roller compacted concrete dams constructed in such areas will face the threat of temperature crack during construction period.Based on cracking mechanism of RCC dam during construction period,finite element simulation algorithm is applied to simulate the development of concrete temperature field and stress field of strong constrained zones of RCC dam during construction period in different day and night difference.According to the calculation results,specific parameters of surface heat preservation and cooling process are optimized.Relevant achievement has reference value to similar engineering.关键词
