Monitoring of fill dam constructed in Ust-Luga on soft foundation soils

Hydraulic engineering

Improvement of fill dams sediment measuring methods and receiving long-term results of in-situ measurements and their analysis is relevant and have a great practical importance for the prediction of possible sediments and, consequently, to enhance the safety of objects on soft foundation soils. The object of this study was the dam as part of a complex for transshipment of liquefied petroleum gases in the commercial port of Ust-Luga. During the work monitoring of facilities was carried out in order to control the security status of hydraulic structures under construction and to evaluate their impact on the environment. The focus in the period of 2010 - 2011 years was given to geodetic control of sediment of the fill dam, which was built on soft foundation soils up to 20...25 m depth.
