Saturation criteria for heavy overconsolidated cohesive soils

Title Pile Aging in Cohesive Soils

This technical note presents the results of a field investigation into pile aging in soft clay which was conducted over a period of ten years. Static load tests were conducted after the excess pore pressure generated by the installation of 6 m long driven concrete piles were fully equalised. These tests allowed the time-capacity aging profile to be established. A normalised capacity-time trend ...

Predictive Model for Normalized Shear Modulus of Cohesive Soils

called maximum shear modulus, Gmax. It can be determined by in-situ methods from the measurements of the shear wave velocity, Vs, by means of crosshole, down-hole, up-hole, or surface wave testing. The relationship between maximum shear modulus and shear wave velocity is rigorous: 2 max s G V    where ρ is soil density. This parameter can be also obtained in laboratory by resonant column or ...

Relation between swelling and erodibility of cohesive soils

A method for measuring the critical shear stress of cohesive soils

Micromechanical-based criteria for the calibration of cohesive zone parameters

This paper presents a new micromechanical model for a collection of cohesive zone models embedded between each mesh of a finite element-type discretization. It aims to forth fully extend the previous linear results of [1] to the calibration of damageable cohesive parameters (cohesive peak stress, critical opening displacement, cohesive energy, etc). The main idea of the approach consists in rep...
