摘要
介绍了鹤洞大桥大体积混凝土结构温度场的测试结果,分析了混凝土产生温度裂缝的原因,提出了温度应力计算及温差控制原则,制定了大体积混凝土浇注的温度控制措施。
The results of mass concrete structure temperature testing of Hedong Bridge were introduced.The reasons caused by concrete temperature were analyzed.The calculation of temperature stress and the principle of temperatuer difference controlling were proposed.The temperature controlling steps were formulated.
