摘要
介绍了天荒坪抽水蓄能电站１＃机组压力管道厂内明钢管段在设计压力作用下的应力状况．实测结果表明，在内水压力值８．６ＭＰａ作用下，压力管道的强度安全系数为３．２，加劲环局部的强度安全系数为２．４，满足设计要求．
The stress state of the exposed penstock for unit No.1 in the power house of the Tianhuangping pumped storage plant,is described.The stress measurement results of this penstock show that the safety factor of strength of the penstock is 3.2 and the safety factor of strength of the stiffening ring is 2.4 under the internal water pressure of 8.6 MPa .Therefore it is satisfied with the design requirement.
