Question 1

1. 
   a)
   Where the preliminary investigation has indicated the feasibility of the project at the site, more detailed site exploration should be under taken. Depending on the results obtained from the preliminary investigation, additional and deeper boreholes may be sunk; more samples extracted (both disturbed and undisturbed); more sounding field tests undertaken to obtain information which shall be sufficient for final design of foundation of structures. Now with the aid of diagram, evaluate the performance of the following exploration methods employed during site investigation of soils:


2. 
   
   Standard Penetration Test (SPT)
   
   


3. 
   
   Dynamic Cone Penetration Test


4. 
   
   Vane Shear Test (VST)
