本發明公開了一種吸力控制的非飽和土綜合試驗儀的系統、裝置以及設計和使用，其特徵是通過一個試樣即可獲得非飽和土在完整吸力範圍內的各種力學特徵和土水特徵。該吸力控制的非飽和土綜合試驗儀可包括吸力控制部分和力學加載部分，可提供多種吸力控制方法和力學加載條件，從而可測試土樣在多種應力狀態和吸力狀態下的特性。該吸力控制的非飽和土綜合試驗儀還可包括螺旋狀水室，其可沖刷通過擴散而聚集的氣泡。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.
