| 摘 要： | 在中联水泥集团南阳分公司水泥熟料生产线二期工程基础底板大体积混凝土的施工过程中,通过温度和应变监测,得出混凝土温度及应变的变化曲线,可随时掌握混凝土中温度应力的发展情况。保证基础底板大体积混凝土施工养护过程中,混凝土的抗拉强度始终大于相应的最大温度拉应力,防止温度裂缝的出现,确保大体积混凝土的施工质量。

| Abstract: | Based on the construction of Zhonglian cement company Nanyang subsidiary second phase clinker cement production line project,temperature and strain monitor tests were conducted to obtaine temperature and strain fluctuation curve. Temperature stress development condition may momentarily be identified.It's useful to guarantee the concrete tensile strength bigger than the corresponding maximum temperature tensile stress along concrete construction.The paper proposed measures to prevent temperature crack and to guarantee mass concrete successful construction. |
