摘要
以青藏铁路桥涵混凝土施工为背景 ,结合特定的施工环境 ,从混凝土内外温差引起的温度应力的角度分析产生表面微裂纹的原因 ;从混凝土强度成长过程中不同时段混凝土内部温差的角度分析产生深层贯穿性裂缝的可能性 ;
An analysis was made of causes for surface cracks due to temperature stress, and the possibility of penetration cracks due to temperature difference. Measures were raised for prevention of surface cracks.
