Experimental analysis of the influence of rheological material and its distribution on time effect deformation characteristics of soft soil

摘要

With the improved direct shear creep apparatus, the rheological material composition and its spatial distribution effects on aging deformation characteristics of soft soil. Four sets are finished including organic clay, quartz and feldspar with different weight percentages and rheological properties of different spatial distribution of sample testing in the same experimental conditions. Test results show that flow in any matter content ratio has significant effects on the rheological properties, the influence of the spatial distribution of waning gradually, and with the uniformity of the distribution and uniformity of the critical value. When a disguised form of size is less than the critical size of soil, soil aging deformation characteristics associated with the flow in a disguised form content ratio, and had nothing to do with the space distribution.
