| Abstract: | Combined with the mass concrete construction of a gas turbine plant foundation,the main construction measures such as assembling reinforcements,installing templates,inbuilding embedded parts and concreting were introduced.The temperature differences between internal and external concrete were controlled and the damaged cracks were avoided by choosing reasonable materials,decreasing the casting temperature,cur-ing concrete and monitoring temperature,et al.Engineering practices show that those construction me... |
