摘　　要：采取有效的温控措施,在保证塔柱混凝土质量的前提下加快施工进度,是斜拉桥主塔冬季施工的关键。以武汉天兴洲大桥主塔中塔柱施工为例,介绍主要的温控措施、冬季施工保温材料的应用效果及工期效应。It is key to the concrete construction of pylons of a cable-stayed bridge in winter season to take effective temperature control measures and accelerate construction progress under the condition that the concrete quality of pylon columns can be ensured. With reference to the construction of the middle column of the pylon of Wuhan Tianxingzhou Changjiang River Rail- cum Road Bridge, this paper presents the principal temperature control measures that should be taken, the effect of application of the thermal insulation materials and their influences on the construction time in the concrete construction in winter season.
