Definition - What does Static Loads mean?
Static loads, otherwise known as dead loads, are loads that don't change with time; they remain constant. Determining static, dynamic and other loading conditions is an important part of the design process for buried pipes.
It is necessary to carry out static load calculations to ensure safe and quality construction of buried pipes and for pipe installation methods such as pipe jacking or direct pipe. These methods are trenchless pipe installation techniques that do not require excavation and are carried out below the earth's surface.
Trenchlesspedia explains Static Loads
Research on static and dynamic load has showed contradictory results regarding the measure of displacement in buried pipes. Some studies show that moving loads produce higher displacement in buried pipes than that produced by static loads, while other studies show otherwise.
However; according to a recent research, it was found that static loads produce a higher displacement of buried pipes than moving loads.
It was also found that the ratio of static to dynamic pipe displacement decreases with increasing pipe stiffness.
