At rest pressure. At rest lateral earth pressure, represented as K 0, is the in situ lateral pressure. It can be measured directly by a dilatometer test (DMT) or a borehole pressuremeter test (PMT). As these are rather expensive tests, empirical relations have been created in order to predict at rest pressure with less involved soil testing, and relate to the angle of shearing resistance.

As this is the very ﬁrst version, surely several small errors will be. Determine lateral earth pressure. Definitions of Key Terms At rest earth pressure coefficient (k0) is the ratio between the lateral and vertical principal effective stresses when an earth retaining structure is at rest (or is not allowed to move at all). Active earth pressure coefficient (ka) is the ratio between the lateral and vertical.

In case of active earth pressure the value of K is Ka, and when the wall moves away from soil, the soil particles will disturbed and the cohesion of soil will decreased, so in case of active earth pressure we subtract the lateral.

Earth Pressure Introduction. Earth pressure is the force per unit area exerted by soil. The ratio of horizontal to vertical stress is called coefficient of lateral earth pressure (K). Earth pressure forces can be at-rest (Fig a), active (b) or passive (c).
Typical range of lateral earth pressure coefficients. The serviceability loss of buried high-density polyethylene (HDPE) double-wall corrugated pipes caused by localized ground subsidence has been reported all over the world.
Beam-on-nonlinear spring model is widely used to analyze the structural responses of buried pipes to the localized ground subsidence underneath the pipe. However, the pipe–soil separation is not considered by the beam-on.

Who can tell me what a "scale model" is. (Listen to student ideas.) A scale model is a smaller or larger version of an object. It is made to be the same as the original object but at a different size than the real object.
You could think of a doll as a smaller scale model of a person. Or a toy car as a smaller scale model of a full-size car.
