内容記述
Double cell type triaxial apparatus was manufactered for trial for the purpose of the consolidation tests of compacted partly saturated soils. Using this apparatus, pore water pressure u_w, pore air pressure u_a, volume change ⊿V, axial displacement and lateral displacement can be measured for the analysis of consolidation.
Under undrained condition, the increment of u_a and u_w with the increment of confined pressure σ_3 was measured. From the results, u_a-u_w is in the range of 0.1-0.3kg/<cm>^^^2 for the compacted soil at and wet of optimum moisture content.
It is measuredand ⊿V, u_a and u_w in the process of consolidation. The large volume change ⊿V_0 is developed at the same time of drainage. The volume change ⊿V-⊿V_0 curve by experiment for that of Terzaghi's one the consolidation of partly saturated soil is progressed more slowly than that by Terzaghi's consolidation theory.
