摘　　要：鉴于某堆石坝施工期实测沉降量沿高程分布规律有显著的特异性,基于沉降观测方法,验证了实测沉降结果的正确性,进而结合该坝坝体填筑进程特点,分析了其施工期沉降的诸多影响因素,认为特异性的产生原因主要在于分期填筑。The settlement of a certain rockfill dam along the elevation distribution is remarkable abnormity during construction period.Based on the method of settlement observation,the accuracy of the measurement results is verified.Combined with the characteristics of the dam filling process,some factors influencing the settlement during construction period are analyzed.It concludes that the main cause of the abnormity is stage filling.
