Abstract:

Thixotropic research on wetland soft soil in Cuihu is carried out by manual vane-shear apparatus. The change of sample’s shear strengths resulted from different stewing times is observed, which can determine the recovery time and recovery degree of shear strength, sensitivity and thixotropic strength ratio. The thixotropy of wetland soil is studied at three depths of soil, which can obtain the coupling effect of depth and stewing time on recovery of soil shear strength. Remoulded samples are studied by different moisture contents tests. The curves of moisture content and shear strength are gained. Test results may provide reference for further study of engineering properties and proper development of wetland soft soil

Key words: wetland soft soil, thixotropy, thixotropic strength ratio, stewing time, different depths
