随着我国跨越大河、海湾的大跨度桥梁中得到了广泛的应用,桥梁承台大体积混凝土被广泛采用。但是,桥梁承台大体积混凝土结构的温度控制是长期困扰施工的难题,其导致裂缝的产生,破坏了结构的耐久性,整体性,影响结构安全和正常使用。本文阐述了对于桥梁承台大体积混凝土的温度控制,从而降低裂缝的发生,对实际施工有一定参考价值。
With our country spanning the great river, the bay’s long-span bridge has been widely used, large-capacity concrete bridge platform is widely used. However, the temperature control of the mass concrete structure of the bridge cap is a long-term problem that plagued the construction, which led to the generation of cracks and undermining the durability and integrity of the structure, affecting the structural safety and normal use. This article elaborates the temperature control of the mass concrete in the bridge cap so as to reduce the occurrence of cracks and has certain reference value for practical construction.
