【摘要】 考虑到陈村大坝的原型观测数据具有较长时间序列的特点,选取每年最不利荷载下的坝顶径向位移值作为监测效应量,应用典型小概率算法,初步拟定了该大坝典型坝段坝顶径向位移的安全监控指标.并利用2012年的观测数据进行大坝运行情况的对比分析.结果表明,该指标符合实际,较为准确,且大坝运行情况良好.更多还原

【Abstract】 According to the characteristics that Chencun dam has a long time series of prototype observation data,we selected the radial displacements at dam crest in the most unfavorable conditions every year as the calculating sequence.We do pilot study of monitoring indices of dam crest radial displacements with small probability method,and intend safety monitoring index of typical dam section.And the monitored data in2012are used for comparative analysis of the dam operation.The results show that the indices are consistent with the actual situation;and the dam operation is in good condition.更多还原
