高寒地区大体积混凝土施工——黄延高速公路裢达沟特大桥承台大体积混凝土施工

Mass concrete construction of alpine region——mass concrete construction of Liandagou Bridge of Huang-Yan super highway

黄延高速公路裢达沟特大桥主墩承台大体积混凝土浇注时,底部约束强,混凝土产生的水化热大,通过采取适当的温控措施,防止温度裂缝的产生。

While the massive concrete pouring of Liandagou Bridge of Huang- Yah super highway with strong bound at the bottom, concrete hydration heat is produced. Proper measures of temperature control prevented the formation of the temperature cracks.
