WebA graph is then plotted of settlement against bearing pressure and will show settlement at any given load. This information is used to calculate the Modulus of Subgrade Reaction, a measure of the stiffness of the subgrade known as the K value. It is expressed as load per unit area per unit of settlement e.g. KN/m2/mm or KPa/mm.

Subgrade Reaction - an overview ScienceDirect Topics

WebSubgrade Modulus is obtained from plate load tests for soil as K = P/S, Where P is Plate Load corresponding to settlement and S is the corrected subgrade modulus for the plate, presented below. The Subgrade modulus value is inversely proportional to the square root of the foundation area up to a base area of 10.0sqm and then remains constant. http://www.findapile.com/p-y-curves/p-y-curves-models Webaddition to the soils survey and analysis and classification of subgrade conditions, the determination of the foundation modulus is required for rigid pavement design. The foundation modulus (k value) should be assigned to the material directly beneath the concrete pavement. However, it is recommended that a k value be established for the … delaware teacher certification reciprocity
