A Calibration Chamber for Cohesive Soils
The paper describes the design and performance of a calibration chamber system for testing in-situ test devices in cohesive soils. Techniques for preparing “undisturbed” clay specimens from a slurry and consolidating them under zero lateral strain K0 conditions are presented. The chamber was used for strain controlled model pressurementer tests during which pore pressure was monitored. Duplicate ...

Preparation of Large-Size Cohesive Specimens for Calibration Chamber Testing
This paper describes the design of an automated slurry consolidometer and calibration chamber system used to prepare largesize cohesive soil specimens for testing in-situ devices, model foundations, and ground anchors. A two-stage technique for the preparattion of homogeneous cohesive specimens subjected to a known stress history is described. Briefly summarized are the data acquisition/control ...

Simplification of Soil Classification Charts Derived from the Cone Penetration Test
This paper presents a semi-empirical approach to simplify existing CPT and PCPT soil classification charts. This approach is based on two tendencies in current charts, namely soil type and in situ soil state. These charts may be simplified into one-dimensional soil classification systems by linear conformal mapping. Accordingly, several charts are simplified, and a comparison to in situ testing ...
