Humidity and osmotic suction-controlled box

摘要

Described herein are systems, apparatuses and methods for the design and use of a suction-controlled box for the measurement of stress-dependent soil and water characteristics, shear strength, volume changes and consolidation characteristics from a single unsaturated soil specimen. The suction-controlled box can include a suction control part and a mechanical loading part, which can apply various suctions and mechanical loadings to test a specimen for a full range of suctions. The suction-controlled box can also include a helical water compartment that can flush diffused air bubbles.

主权项

1. A suction-controlled box, comprising:
a suction control part that facilitates manipulation of a suction of a single soil specimen; and a mechanical loading part that facilitates measurement of a displacement for a loading of the single soil specimen, wherein the suction-controlled box is configured to determine at least four soil properties for the single soil specimen.
