摘要
为满足设计要求,避免产生温度裂缝,确保大桥的使用寿命和运行安全,陕西秦地建设有限公司联合科研单位对承台大体积混凝土进行了温度场及应力场仿真计算,根据计算结果制定了不出现有害温度裂缝的温控标准及相应的温控措施以保证工程质量。
In order to meet the design requirements,avoid the generation of temperature cracks,and ensure the service life and operation safety of the bridge,in cooperation with some scientific research institutions,Shaanxi Qindi Construction Co.,LTD carried out the calculation of the temperature field and stress field simulation for bearing platform＇s mass concrete,and according to the calculation results,works out the temperature control standards for avoiding the occurrence of harmful temperature cracks and corresponding temperature control measures for ensuring the project quality.
