Custom Soil Static Lateral Pressure Coefficient Tester for Soil Lab Testing Axial loading 0-10kN Manufacturer, Quotes

The static lateral pressure coefficient is the ratio of the effective lateral stress to the effective axial stress of soil under conditions of no lateral deformation.
The static lateral pressure coefficient of soil is calculated by determining the effective lateral stress and effective axial stress using a pressure gauge in drained or undrained tests, and is applicable to saturated clayey and sandy soils.
