| Abstract: | The foundation raft in Chengdu Aerospace Science and Technology Building project is 80.9m long from east to west,56.35m wide from south to north.The main building foundation slab is 3.5m thick.Based on structure characteristics,the foundation slab is separated into four parts to construction.Through the construction practice of the 3.5m thick foundation slab,this paper introduces the construction technology and scheme optimization of mass concrete bedplate foundation from binding and installation of steel bar,late poured band formwork setting,and mix proportion design of concrete.The concrete monitoring techniques adopted to ensure the quality of mass concrete construction is also showed.All these measures make the slab has no cracks since the end of construction. |
