抽水蓄能电站引水系统钢衬变形和应力实测资料分析

摘要

Based on existing monitoring data of displacement and stress in embedded penstocks from constructed pumped storage power stations.The results show that the data of displacement or deformation in penstock,cushion and rock are all very small,and the sharing ratio of internal pressure in bedrock can reach to ?％.The results have important value not only on the verification and comparison of simulation,but also on the engineering design in other similar hydropower projects.%本文通过分析已有抽水蓄能电站实测资料,发现在设计内水压力作用下,钢衬、垫层和围岩中的位移监测值均甚小;通过反算,围岩分担率可达83％.上述认识对数值仿真分析的验证和对比具有重要意义,也对类似工程设计具有一定的参考价值.
