【摘要】 针对深溪沟水电站河床式厂房底部的填塘碾压混凝土,利用有限元方法,计算各种温控措施条件下的温度和应力,并筛选出合理的温控措施,使填塘碾压混凝土在该温控措施条件下的最高温度和最大应力均能满足温控标准的要求。同时研究在推荐的温控措施下,填塘混凝土浇筑块表面点和中心点的温度变化对温度场的影响,为类似工程的温控措施提供参考。更多还原

【Abstract】 Based on finite element analysis,temperature and stress of backfill RCC of Shenxigou Hydropower Project run of river power house base are calculated under various temperature control conditions,and the reasonable temperature measures are selected so that the maximum temperature and stress of the backfill RCC under this temperature control condition can meet the specified temperature control requirements.Meanwhile,under the commendatory temperature control condition,temperature variations of the RCC surface points and centrol points can be used as a reference for the similar projects.更多还原
