大坝水平位移监测是重力坝在运行期运行工况的重点监测项目,对监测数据进行分析是准确掌握大坝的运行状态关键。文章通过对岩滩大坝坝顶和观测廊道水平位移的长系列观测资料建立多元逐步回归统计模型,构建水平位移与原因量之间的定量关系,并根据建立的回归模型,对岩滩大坝水平位移实测值进行分析,找出对水平位移有主要、次要和没有影响的因子,有助于了解大坝水平位移变化规律,准确掌握大坝的工作状态。

The horizontal displacement monitoring of the dam is the key monitoring item of the operation condition of the gravity dam during the operation period. The analysis of the monitoring data is the key to accurately grasp the operation state of the dam. Based on the long series of observation data of horizontal displacement of Yantan dam crest and observation gallery, this paper establishes a multiple stepwise regression statistical model, constructs the quantitative relationship between horizontal displacement and cause quantity, analyzes the measured value of horizontal displacement of Yantan dam according to the established regression model, and finds out the factors that have primary, secondary and no influence on horizontal displacement, which is helpful to understand the variation law of horizontal displacement of the dam and accurately grasp the working state of the dam.
