Here are some processing solutions, wherein each solution is specific analyzes; the advantages and disadvantages of each solution were made:
II.2.2.1 When HDY soft soil thickness <2m:
In this case, we just need a base of reinforced sand cushion combined with a layer of geotextile (blister geotechnical) to increase shear strength for soft ground below.
