摘要
介绍了小浪底工程的概况和近坝岸 (边 )坡外部变形观测的必要性 ,然后对监测系统的方案设计与监测情况进行了叙述 ,用常规分析的方法对观测数据进行了分析 ,最后采用统计学中的逐步线性回归方法 ,对位移量较大的某一测点建立了位移量的数学模型 ,并进行了回归拟合和预报 .
First, the paper gives a brief introduction to the Xiaolangdi project and the necessity of monitoring the external deformation of near-dam bank slope. Then the design of the monitoring system is introduced, and conventional method is used to analyze the monitoring data. And finally stepwise linear regression is employed to build up a mathematical model of one location where large displacement occurs, furthermore, regression fit and forecast are made.
