结合某心墙堆石坝的实际,对施工期沉降管以及水管式沉降监测数据进行整理,对其沉降变化规律以及坝体不均匀沉降进行综合分析。结果表明:竣工时坝体最大沉降量不是发生在坝体顶部,而是发生在坝体中部高程处。各测点沉降量在时间上与填筑进度具有良好的关联性,压缩模量的差异大小是不均匀沉降梯度大小的关键影响因素,坝体填筑时应对材料模量相差较大的部位采取相应的防止不均匀沉降的措施。 Combined with the actuality of a core rockfill dam, the monitoring data of settlement pipe and water pipe settlement during construction are sorted out, and the regularity of settlement change and uneven settlement of dam body are analyzed. The results show that the maximum settlement of the dam body does not occur at the top of the dam when it is completed, but occurs at the mid elevation of the dam body. The settlements of each measuring point have a good correlation with the filling progress in time. The difference of compressive modulus is the key influencing factor of the uneven sedimentation gradient. When filling the dam, the difference of material modulus should be taken The corresponding measures to prevent uneven settlement.
