摘要
通过对鱼简河拱坝的仿真分析,确定分缝方案和温控措施.研究结果表明,通过分4条缝、掺3%-4%的MgO并在11月至次年5月完成混凝土碾压,只须进行常规的养护而不必采取其他特殊温控措施即可以满足混凝土的抗裂要求,达到快速施工的目的.
Based on the simulation made on RCC arch dam on Yujianhe River, the temperature control measures with the construction jointing plan are determined. According to the numerical results of the simulation, the temperature control measures to prevent cracks are to be taken as the follows: two normal joints and two inducing joints are arranged, while the concrete is mixed with 3% -4%MgO; with which the anti-cracking requirement can be met and the quick construction can be realized as well.
