Open publisher page 0 citations

Abstract

Based on the observations on Fengman Dam, statistical analysis was done on horizontal displacement in dam crest applying with the method of stepwise regression analysis. The result indicated that horizontal displacement was relative to reservoir water level, temperature and time, among which temperature and reservoir level were main factors, while time had a little influence. Some suggestions were put forward to supply beneficial basis to the safety of Fengman Dam.
