Effect of disturbance



[6] Theory
[ Type 1 ] Standard penetration test: SPT
Set up the SPT sampler at end of the road
Hammer = 63.5 kg / Height = 76 cm
Number of Impact - interpenetrate 30 cm
Last two times (30 cm) , First time : disturbed
Delicate ground , Dense sandy soil
[6] Theory
[ Type 2 ] Effect of disturbance
Line = Most Ideal sample / disturbed value = 0
Dotted line = Division sample , drilling sample , etc
Show ( Vv/Vs = e )
Can compare disturbed value - each type
[7] Conclusion
Video Shows..
Explain basic theory Samplers
Subsurface / Ground Properties
Environmental disturb elements
