摘要
为分析施工期混凝土拱坝的温度场性态、防止温度裂缝,提出一种施工期混凝土拱坝温度监测资料分析法,并以某混凝土拱坝为例,介绍了温度计的布置及温控措施,分析了温差与温度计测值变化规律。根据温度计测值绘制了典型坝段的温度计等值线,并分析了温度场分布。结果表明,温度计布置合理,采取的温控措施行之有效,可供借鉴。
In order to analyze the temperature field behaviors of concrete arch dam during construction period and prevent temperature cracks, this paper proposes a analysis method, which is used to analyze temperature monitoring data of the concrete arch dam during construction period. Taking a certain concrete arch dam for an example, arrangement of the thermometers and temperature control measures are presented. It also analyzes the changing principles of the temperature value and the difference in temperature. Furthermore, the temperature-contour map of the representative dam sections are plotted and the temperature field distribution is analyzed in terms of the temperature monitoring values. The results show that the arrangement of the thermometers is reasonable and the temperature control measures are effective. It provides reference for engineering application.
