Fredlund土水特征曲线压力板仪（SWCC）装置是一套简便的非饱和测试装置，由加拿大工程院院士D.G Fredlund教授设计，可以在不同的应力路径下，施加基质吸力。

Explore accurate soil-water characteristic curve (SWCC) determination with GCTS's solutions: SWC-050 and SWC-150. SWC-050 offers an economical way to analyze up to three samples simultaneously, applying suctions up to 500 kPa.

The Fredlund SWCC Device is a simple unsaturated soil testing apparatus with great flexibility for applying matric suctions while following various stress paths. The device can be used to obtain the complete soil-water characteristic curve, SWCC, for a soil.

The SWC-150 can be used to obtain the complete soil-water characteristic curve (SWCC) for a soil sample. The Fredlund SWCC device allows the operator to control matric suctions from near zero values up to 1,500 kPa (215 psi), and is capable of applying one-dimensional loading, Ko, to a specimen with a diameter up to 75 mm.

2022年8月19日 · A new SWCC device was developed for measuring the SWCC at very low suctions (i.e., smaller than 1 kPa). The device has a large specimen chamber as 300 mm in diameter and 150 mm in height, which is suitable for coarse soils.

2020年12月9日 · Soil–Water characteristic Curve (SWCC) is meant to describe the mechanical behavior of unsaturated soil. The present paper focuses on the internal multi-scale...

2005年6月27日 · To quantify the matric suction of the sand, a SWCC was developed experimentally using a modified unsaturated one-dimensional oedometer (K 0 ) device, i.e., the Fredlund device, manufactured...

土水特征曲线是描述非饱和土特性的重要曲线, 准确测量该曲线是非饱和土力学研究的关键之一。本文基于gcts土水特征曲线(swcc)仪对原状黄土进行试验, 研究影响试验的各种因素及相关异常现象。实验结果表明:(1)由于兰州气候干燥和试验周期长, 蒸发效应在试验 ...

2007年9月6日 · A new oedometer device for SWCC determination has been evaluated by testing a wide range of soil types, and recommendations for best practices for use of this device have been made. The new device allows application and control of the net normal stress, σ − u a, in addition to the matric suction, u a − u w. Thus it can be used to simulate ...

The GCTS SWC-050 provides an economical and reliable way to determine the soil-water characteristic curve on up to three samples simultaneously. This system includes three cells that connect to a single pressure application system to apply suctions up to 500 kPa.
