摘要
温度场关乎着大体积混凝土工程施工期的安全与健康,埋设冷却水管作为最常见的温度控制措施,对含水管混凝土温度分析方法的研究有重要的科学意义与实际应用价值,其实质是小口径管内循环流体与固体间的传热分析问题。文章阐述了关于大体积混凝土埋设冷却水管的温度场分析方法的研究现状、进展和未来发展方向。首先,对含水管混凝土传热问题进行了描述。然后,介绍了数学求解方法、伪三维化方法、常规有限单元方法、改进有限单元法等含水管混凝土温度场分析方法,并讨论了各分析方法的优缺点。最后,从学科发展与实际应用的角度展望含水管混凝土温度场分析方法的未来发展方向。
Temperature field is of great importance to the safety and health of mass concrete in construction phase and embedding cooling pipes is the most commonly applied thermal control method. The analysis of temperature field within such mass concrete is a key part of the design. This paper presents a review of the history and state-of-the-art and a future prospect of the methods. First, the application history is reviewed in brief. Then, we discuss the major methods and their pros and cons, such as the analytical solution method, pseudo-3 D method, FEM with refined meshes, equivalent effect method, substructure method, and CEM. Finally, future trends are discussed on theoretical and practical needs and development.
