摘　　要：通过对崖门大桥施工过程温度效应的理论分析与现场实测,揭示了大桥在不同施工阶段下的温度影响规律,从而为补偿温度效应、准确给定立模标高以及寻找合理的标高、索力测量时间提供了科学的依据。有关成果对于在同类型大跨度混凝土斜拉桥施工过程中把握温度影响规律、有效消除温度效应有一定的参考价值。This paper illustrates the temperature effect law at different stages of construction of Yamen Bridge, and provides the scientific bases for temperature effect compensation, correct determination or reasonable selection of formwork elevation, and proper time for cable force measurement in accordance with the theoretical analysis and field measurements of the bridge under construction. The results presented in the paper are of certain reference to the understanding and effective reduction of temperature influences during the construction of longspan concrete cablestayed bridges of similar kind.
