In order to investigate the shear characteristics of earth structure after construction.
Four sample soils with different gradation were selected and compacted under the optimum moisture content and the maximum dry density.
And the direct shear test and the triaxial compression test were performed with those sample soils under various pre-compression loads.
The results were summarized as follows ;
1. With the increase of the percent passing of No. 200 sieve, the cohesion of soil increased regularly and the internal friction angle of soil decreased with slow ratio.
2. The pre-compression increased the shear strength of compacted cohesive soil. The increase of cohesion was very apparent but the internal friction angle didn't show such regular tendency.
3. With the increase of pre-compression load, the slope of stress-strain curve showed steep at the early stage of horizontal strain. The vertical stratin was small at the compression stage and big at the expansion stage.
4. When the vertical stress of shear test with increase in the horizontal strain was small, stress ratio (shear stress vs. vertical stress) of sample showed the largest value and the slope of stress ratio curve showed also steep.
5. When the sample was had the same condition, the cohesion of soil showed bigger value in the triaxial compression test and the internal friction angle of soil showed bigger value in the direct shear test.
