摘要：

某混凝土重力坝自2019年以来，位于32号坝段的倒垂线测点每年6—9月所测数据存在异常突变，测值变幅大。通过监测资料分析和现场检查、测试，查明了测值突变的原因，并改变了倒垂线的观测方法，使其恢复正常运行，可为类似工程情况提供借鉴。

Abstract:

Since 2019, the inverted plumb line measuring points in the dam section No. 32 of a concrete gravity dam have shown abnormal abrupt changes with large amplitude in measurements from June to September every year. By analysis of monitoring data, on-site inspections and tests, the causes of the abnormal abrupt changes in measurements have been identified, and the observation method of the inverted plumb line has been adjusted to restore its normal operation, providing reference for similar situations.
