Strength of Dilating Soil and Load-holding Capacity of Deep Foundations: Introduction to theory and practical applications [Hardcover]

Introduces the theory and practical application of dilating soil and the load-holding capacity of deep foundations. Topics covered include dilatancy as a fundamental property of granular media, direct shear in conditions of constrained dilatancy, and load-holding capacity of a single pile.Introduction -- Part 1: Strength of dilating non-cohesive soil -- 1 Dilatancy as a fundamental property of granular media -- 1.1 On the term dilatancy -- 1.2 Interaction of grains in non-cohesive soils -- 1.3 Changes in soil density in the process of failure -- 1.4 Plastic and elastic deformations of non-cohesive soils -- 1.5 Dilatancy and the stress condition of soil -- 1.6 Examples of free and constrained dilatancy -- 1.7 Manifestation of dilatancy in soil strength tests -- 1.8 Conclusion -- 2 Models of elasto-plastic deformations of dilating non-cohesive soil -- 2.1 General propositions -- 2.2 Models of contact shear -- 2.3 Soil-to-soil shear model -- 2.4 Model of internal bulge -- 2.5 Justification of the assumption regarding elastic reaction of the massif to dilatancy -- 2.6 Conclusion -- 3 Instruments and methods for soil testing in the conditions of constrained dilatancy -- 3.1 General propositions -- 3.2 Dilatometric Apparatus of Contact Shear (DACS) -- 3.3 Dilatometric Apparatus of Direct Shear (DADS) -- 3.4 Special testing method with the use of the serial shear apparatus BCB-25 -- 3.5 Dilatometric Apparatus of Contact Shear of reinforcing elements (DACS-A) -- 3.6 Dilatometric Triaxial Apparatus (DTA) -- 3.7 Conclusion -- 4 Contact shear in conditions of constrained dilatancy -- 4.1 General propositions -- 4.2 The influence of dilatancy constraint on resistance of soil to contact shear -- 4.3 Dilatant component of strength as a function of massif elasticity -- 4.4 Angle of contact friction as a function of massif elasticity -- 4.5 The influence of initial soil density and grain size -- 4.6 Influence of moisture content -- 4.7 Values of dilatant strains -- 4.8 InfluenclÃl
