4.1 Loess Moistening Deformation Calculation Method
Consolidation compression tests of undisturbed soil samples in typical
loess site with different water contents under 200kPa load conditions
were carried out, and the curve was fitted as shown in Fig. 9.
[Insert Figure 9]
The moistening deformation curve was fitted using Eq. (2):
where y is the vertical deformation of the 20-mm thick soil layer
in mm and θ is the moisture content.
At the position of P i (i=0,1,2…4), the
initial water content was θ i0 and the initial
vertical deformation was yi0 . At the timet , the water content and vertical deformation atP i were θ t0 andy it, respectively. The moistening deformation
calculation diagram is given in Fig. 10.
