An excavation was made in sandy soil and soil

samples were collected at depths of 2ft 4ft,

and 6 ft. Ground water was encountered at depth of 5 ft. Soil sample at 2ft

was dry. Soilsample at 4ft was tested in the lab and moisture content of 8.3% was determined. Assuming void ratio of 0.5 determine:

a)Unit weight (lb/ft3) of soil at 2ft(110.24pcf)

b)Unit weight (lb/ft3) of soil at 4ft(119.39pcf)

c)Moisture content (%) of soil at 6ft(18.87%)

Step 1

We have been given the following information:

Step 2

With given data we can draw the following diagram:

Step 3

a) Bulk unit weight at 2ft: ...
