New Approach to Analysis of Consolidation Data at Early Times
Autor: John T. Christian, Charles C. Ladd, Alfredo Urzua
Publikováno v: Journal of Geotechnical and Geoenvironmental Engineering. 142
If U¯v>0.50, Asaoka’s method can be used to evaluate cv(s) and scf from settlement data, but the method leads to unsafe results when the data are measured when U¯v

Small-Strain Nonlinearity of Normally Consolidated Clay
Autor: Charles C. Ladd, John T. Germaine, Marika Santagata
Publikováno v: Journal of Geotechnical and Geoenvironmental Engineering. 133:72-82
This paper addresses the small-strain undrained shear behavior of clays based on an extensive testing program conducted on normally consolidated resedimented Boston blue clay (RBBC). The uniformity and reproducibility in the behavior of this soil per

Factors Affecting the Initial Stiffness of Cohesive Soils
Autor: Marika Santagata, Charles C. Ladd, John T. Germaine
Publikováno v: Journal of Geotechnical and Geoenvironmental Engineering. 131:430-441
The paper presents the results of an extensive laboratory program conducted to establish the factors affecting the initial stiffness (Young’s modulus) of cohesive soils in undrained triaxial compression. The testing program, conducted on resediment

Triaxial Testing of Frozen Sand: Equipment and Example Results
Autor: Gregory Da Re, Charles C. Ladd, John T. Germaine
Publikováno v: Journal of Cold Regions Engineering. 17:90-118
This paper describes a high-pressure, low-temperature triaxial testing system that has been specifically designed and built at the Massachusettes Institute of Technology in order to study the physical mechanisms controlling the strength-deformation b

Effects of Disturbance on Undrained Strengths Interpreted from Pressuremeter Tests
Autor: Andrew J. Whittle, Charles P. Aubeny, Charles C. Ladd
Publikováno v: Journal of Geotechnical and Geoenvironmental Engineering. 126:1133-1144
Although the cylindrical cavity expansion theory should provide a sound basis for obtaining the undrained shear strength of clays from pressuremeter tests, the interpreted strengths are often inconsistent with data measured in high-quality laboratory
