What is the DSM settlement system to monitor settlement in embankment fills and foundation soil?
The DSM settlement system consists of four main components: a string of DSM pressure gauges, a liquid filled tubes, electric cables and a DSM reference gauge with reservoir of liquid. The DSM pressure gauges are embedded in the soil and by tubing connected to the DSM reference gauge which shall be located at higher elevation on a stable ground, away from the construction activities. The DSM pressure gauges measure the pressure created by the liquid column in the tubing. The height of the liquid column is equal to the difference in elevation between the DSM pressure gauges and the DSM reference gauge. Electric cables provide connection to ADK-10 data acquisition unit for automatic monitoring.
