Seepage of a high core rockfill dam is mainly affected by factors such as water level, rainfall, temperature, filling height, and aging. The traditional research method is to establish a multiple linear regression model to analyze the influence factors of seepage. However, the multicollinearity between these factors affects parameter estimation, and random errors in the data cause the regression model to fail to be established. This paper starts with data collected by an osmometer, uses the 3\u03b4 criterion to process the outliers in the sample data, uses the R language to perform principal component analysis on the processed data to eliminate the multicollinearity of the factors, and finally uses multiple linear regression to model and analyze the data. Taking the Nuozhadu high core rockfill dam as an example, the influencing factors of seepage in the construction period and the impoundment period were studied and the seepage was then forecasted. This method provides guidance for further studies of the same type of dam seepage monitoring model.<\/jats:p>","DOI":"10.3390\/s18092749","type":"journal-article","created":{"date-parts":[[2018,8,21]],"date-time":"2018-08-21T11:12:42Z","timestamp":1534849962000},"page":"2749","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":27,"title":["Research on a Seepage Monitoring Model of a High Core Rockfill Dam Based on Machine Learning"],"prefix":"10.3390","volume":"18","author":[{"given":"Xiang","family":"Cheng","sequence":"first","affiliation":[{"name":"State Key Laboratory of Information Engineering in Surveying, Mapping and Remote Sensing, Wuhan University, Wuhan 430079, China"}]},{"given":"Qingquan","family":"Li","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Information Engineering in Surveying, Mapping and Remote Sensing, Wuhan University, Wuhan 430079, China"},{"name":"Key Laboratory of Geo-environmental Surveillance in the Maritime and Marine Zones, National Mapping and Geographic Information Bureau, Shenzhen University, Shenzhen 518061, China"}]},{"given":"Zhiwei","family":"Zhou","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Geodesy and Earth\u2019s Dynamics, Institute of Geodesy and Geophysics, Chinese Academy of Sciences, Wuhan 430077, China"}]},{"given":"Zhixiang","family":"Luo","sequence":"additional","affiliation":[{"name":"Key Laboratory of Geo-environmental Surveillance in the Maritime and Marine Zones, National Mapping and Geographic Information Bureau, Shenzhen University, Shenzhen 518061, China"}]},{"given":"Ming","family":"Liu","sequence":"additional","affiliation":[{"name":"Guizhou Water Conservancy and Hydropower Survey and Design Institute, Guiyang 550000, China"}]},{"given":"Lu","family":"Liu","sequence":"additional","affiliation":[{"name":"Guizhou Water Conservancy and Hydropower Survey and Design Institute, Guiyang 550000, China"}]}],"member":"1968","published-online":{"date-parts":[[2018,8,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"269","DOI":"10.1016\/j.compgeo.2010.10.004","article-title":"Settlement analysis of the shuibuya concrete-face rockfill dam","volume":"38","author":"Zhou","year":"2010","journal-title":"Comput.
