我公司的所有产品均按国家标准组织生产，产品质量稳定可靠， u型混凝土膨胀剂uea是中国建筑材料研究院一项重大科研成果。 - This article incorporates with the practice for construction of mass concrete foundation structure of handan big world department store , according to the features in foundation structure design and the conditions of winter construction in this region , introduces micro - expansion concrete mix proportion design , pouring technology for mass concrete structure , the solution of the strengthen joint - strip and post - pouring joint strip in concrete foundation work , and temperature control for mass concrete
结合大世界商城底板大体积混凝土的施工实例，针对基础结构的设计特点和当地冬季施工的气候条件，介绍了补偿性混凝土配合比设计、大体积混凝土浇筑工艺、基础混凝土加强带和后浇带施工工艺、底板混凝土温度控制和自动化监测等多项综合性技术。 - Secondly , the producing mechanism of crack in reinforced structure and factors which affect crack have been discussed , in the emphasis , the method is expounded , which applies first releasing then resisting , combination of releasing and resisting . in the method , flexible slit is applied firstly , which can make deformation of structure distributed , and decrease deformation energy , then the tiny expansion concrete and prestressed concrete with unbonded tendons are applied . and in the different phase , the compressive prestress is put on the concrete structure
其次，分析并论述了钢筋混凝土结构裂缝产生的机理和影响因素，着重阐述了“利用先放后抗，抗放结合，综合控制”的方法：即首先利用后浇带，使混凝土结构分段变形，减小超长变形的影响；并采用微膨胀混凝土技术及无粘结预应力混凝土技术，分阶段对混凝土结构施加一定的预压应力，从而减小或完全抵消混凝土结构因混凝土硬化收缩引起的拉应力；再结合一些其他措施，成功实现钢筋混凝土结构的超长无缝设计与施工。
