高层建筑对地基基础的稳定性和坚固性要求很高。随着建筑高度的增加,基础深度也相应增加,因而增加了基础施工的复杂性。在基础施工中大体积混凝土的施工是关键。如何能不间断地一次浇筑上万立方米的混凝土,并能控制水泥水化热所引起的混凝土升温、降温及收缩各阶段产生的裂缝,已成为大体积混凝土施工的重点。
High-rise buildings on the foundation of the stability and robustness demanding. As the height of the building increases, the base depth also increases accordingly, thus increasing the complexity of the foundation construction. In the basic construction of mass concrete construction is the key. How to pour tens of thousands of cubic meters of concrete at a time without interruption and control the temperature rise, temperature drop and shrinkage of the concrete caused by the heat of cement hydration has become the focus of mass concrete construction.
