Abstract
Taking a large commercial complex building in Nanjing,Jiangsu as an example,this paper analyzes the variation of temperature and stress of concrete silo block with time by setting monitoring points at different characteristic points of concrete silo block during construction,and puts forward effective crack control measures.Practice shows that the temperature changes with time at different positions of concrete silo block are basically the same,the temperature change rate is related to the heat dissipation boundary,and the temperature cracks are more like-ly to occur at the concave corner of concrete than other positions,which should be paid attention to in the construction process.关键词
