摘要
提出了一种基于红外热成像技术的混凝土桥梁结构表面温度连续监测的新方法,并分析其表面温度场分布特征及影响因素。监测结果表明:红外热成像技术是一种简便、高效、准确的混凝土结构和构件温度监测的新方法,可以用于评价结构受环境温度影响的程度、结构温度应力产生的机理和预测混凝土材料温致病害的潜在风险。
A method for continuously monitoring the surface temperature of bridge structure was proposed by using the in- frared thermography technology. The surface thermal field is established and the effects of various factors on the surface tem- perature were analyzed. The method provided comprehensive data for evaluating the effects of environmental factors on the temperature fields of the concrete structure, the mechanism of temperature effects on the thermal stress, and the risks of thermally induced concrete defects.
