The invention relates to an earth and rockfill dam deformation safety monitoring visualization system. The system comprises a three-dimensional scene information platform, a data preprocessing module, a deformation data modeling analysis module and a dam body deformation forecasting and early warning module. The three-dimensional scene information platform establishes a three-dimensional scene model of a project through an unmanned aerial vehicle oblique photography modeling technology, and provides a platform for other function module operation and analysis result display; the data preprocessing module is used for extracting effective information in earth and rockfill dam deformation monitoring data; the deformation data modeling analysis module is used for sequentially establishing point, line, surface and body monitoring models of measuring points by using a statistical model space modeling method; and the dam body deformation forecasting and early warning module is used for forecasting and early warning the deformation state of the dam and judging the operation safety state of the dam body based on the actually measured deformation value. According to the method, the three-dimensional scene information platform of the earth and rockfill dam is established, so that the visual feeling of a user on a project is improved, the dam deformation data is processed and analyzed on the basis, and a multi-level monitoring model is established to represent the overall deformation characteristics of the dam body, so that the operation state of the earth and rockfill dam is accurately monitored.
