1998年 8月，为了减轻长江中下游的防洪压力，清江隔河岩水库蓄水一度超过正常蓄水位 3 m多。以清江隔河岩大坝部分监测点的变形观测数据为例，详细介绍了大坝变形预测模型的建立方法，且运用一个实例验证了该方法的有效性。
In August 1998, in order to reduce flood control pressure in the middle and lower reaches of the Yangtze River, the Geheyan reservoir in the Qingjiang River once exceeded the normal water level by more than 3 m. Taking deformation observation data of some monitoring points of Geheyan dam in Qingjiang River as an example, the establishment method of dam deformation prediction model is introduced in detail. An example is given to verify the effectiveness of the method.
