为了保证溪洛渡水电站地下厂房岩锚梁的结构安全,研究进一步采取综合温控措施防裂的有效性和合理性,通过对地下厂房岩壁吊车梁在春季和夏季施工进行三维仿真分析,得到温度场和应力场的分布及其随时间的变化规律并进行分析比较,同时分析了春夏两季裂缝产生的不同原因,为以后的裂缝处理提供了参考依据。 In order to ensure the structural safety of the rock anchor beam in the underground powerhouse of Xiluodu Hydropower Station, the effectiveness and rationality of further temperature control measures against cracking are further studied. Through the three-dimensional simulation analysis of the rock-wall crane beam construction in spring and summer, the temperature field And the distribution of stress field and its variation with time are analyzed and compared. At the same time, the different causes of cracks in spring and summer are also analyzed, which provides a reference for future crack treatment.
